Linear Module Guide: Buy from Zhejiang Sikete Technology Co., Ltd.
What Is a Linear Module and Why It Matters in Modern Automation
A linear module is an integrated motion assembly that converts the rotary output of a motor into controlled, repeatable linear travel. Inside a typical unit you will find a rigid aluminium alloy profile, a precision guide rail or bearing carriage, a drive element such as a ball screw or timing belt, and a mounting interface for the motor. Because all of these parts are engineered to work together as one sealed system, a linear module removes the alignment problems, tolerance stacking, and assembly errors that plague homemade motion stages. Engineers specify a linear module whenever a machine must move a tool, camera, gripper, or sensor along a straight path thousands of times per hour without losing position. In packaging lines, CNC routers, pick-and-place heads, and laser cutting systems, the linear module is often the single component that decides the accuracy of the finished product. That is exactly why choosing the right linear module supplier matters as much as choosing the right motor or controller.
Modern automation has moved toward higher cycle rates, tighter tolerances, and smaller footprints, and a well-built linear module supports all three at once. A precision linear module can hold sub-0.01 mm repeatability while running continuously in a three-shift factory, which reduces scrap and rework dramatically. When machine builders replace pneumatic cylinders with an electric linear actuator, they usually gain programmable positions, gentler acceleration curves, and far lower energy consumption. Reliability also improves, because a sealed linear module keeps dust and chips away from the rolling elements that would otherwise wear out quickly. Downtime is expensive, and a single failed linear motion axis can stop an entire production cell for hours. Selecting a proven linear module platform therefore protects both product quality and overall equipment effectiveness.
Zhejiang Sikete Technology Co., Ltd. builds its business around that idea: precision linear motion hardware that is engineered for real production environments rather than laboratory conditions. The company designs and manufactures linear modules, motorized stages, ball screws, and related automation components for machine builders, integrators, and distributors around the world. Buyers who want to understand the full catalogue can start at the HOME page, where the main product families, certifications, and factory capabilities are presented clearly. Whether you are replacing a worn axis on an existing machine or designing a brand-new automated line, the goal is the same: a linear module that delivers the promised stroke, load, and accuracy for years. The rest of this guide explains how Sikete linear modules achieve that, and how to order the right configuration for your application.
Company Overview: ZHEJIANG SIKETE TECHNOLOGY CO., LTD.
Zhejiang Sikete Technology Co., Ltd., often shortened to SKR, is a Chinese manufacturer of precision linear motion and automation components founded in 2011. Over more than a decade the company has grown from a component workshop into a vertically integrated factory that handles machining, assembly, inspection, and testing under one roof. Its product programme covers precision slide tables, synchronous belt slides, linear motor stages, and gear rack drives, which means almost any linear motion requirement can be met from a single source. Because Sikete sells directly to OEMs and system integrators, buyers deal with the people who actually build the product rather than with a chain of middlemen. The company's experience is documented on the ABOUT page, which outlines its vision, team, core advantages, and key statistics such as completed projects and years of engineering experience.
Manufacturing depth is one of the strongest arguments for sourcing from Sikete. The factory operates CNC machining centres, precision grinding equipment, profile extrusion and anodising lines, and dedicated assembly cells for linear module production. Each unit passes through dimensional inspection, running-in tests, and accuracy verification before it is packed, and inspection records can be supplied with the shipment when required. This level of process control is what allows the company to publish tight specifications for stroke accuracy, parallelism, and repeatability on every linear module series. Buyers who want to verify capability before committing to a large order can request samples, video inspections, or a factory audit. Ongoing company milestones and exhibition activity are regularly published on the NEWS page, which gives overseas customers a sense of how active and stable the business is.
For international buyers, working with a Chinese linear module manufacturer often raises questions about communication, documentation, and consistency. Sikete addresses these concerns with English-speaking sales engineers, standardised technical datasheets, and clearly defined quality control procedures at every production stage. The company also supports OEM and ODM projects, so a customer's own branding, colour, connector type, or control interface can be built into the linear module rather than added afterwards. Because the factory controls its own supply chain for aluminium profiles and machined parts, lead times are predictable even when order volumes spike. That combination of engineering support, vertical integration, and direct pricing is what makes Sikete a practical long-term partner rather than a one-off vendor.
Key Advantages of Sikete Linear Modules
High Precision and Repeatability for Demanding Motion Control
Sikete linear modules are built around ground ball screws, precision linear guides, and rigid machined housings that together produce excellent positioning accuracy. Repeatability is typically held within a few microns on ball screw versions, which is essential for applications such as dispensing, optical inspection, and semiconductor handling. Because the guide rail and the drive screw are machined and mounted on the same reference surface, angular errors and cantilever effects are minimised from the start. Each unit is lapped and preloaded so that backlash is virtually eliminated, giving smooth motion in both directions. Thermal stability is also considered, since symmetrical profile geometry helps the linear module maintain accuracy as it warms up during long production runs. For engineers who need dependable precision linear module performance rather than a theoretical specification sheet, this matters enormously.
Rigid Aluminium Alloy Structure for Stability and Reduced Vibration
The extruded aluminium alloy profile used in every Sikete linear module is thick-walled and internally ribbed, which raises stiffness without adding unnecessary mass. High rigidity directly reduces deflection under load, so the carriage stays on its intended path even when a heavy gripper or welding torch is mounted at the end of a long stroke. Lower structural vibration also means shorter settling times, allowing the axis to reach position faster and raise the machine's effective throughput. The anodised surface resists corrosion and abrasion, keeping the module looking and performing like new in dusty or humid workshops. Multiple mounting planes and T-slots are machined into the profile, so sensors, cable chains, and tooling can be attached without drilling into critical surfaces. The result is a linear motion axis that behaves predictably across thousands of working hours.
Smooth, Low-Noise Operation with Long Service Life
Noise is often overlooked during machine design, but it becomes a serious issue in laboratories, medical equipment, and clean assembly areas. Sikete belt-driven linear modules use high-quality polyurethane belts with steel reinforcement, running quietly even at speeds above one metre per second. Ball screw versions use precision-ground screws with recirculating ball nuts, lubricated for life in many standard configurations. Because the rolling elements are protected by seals and wipers, contamination ingress is limited and service intervals are extended. Customers frequently report that a Sikete linear module still meets its accuracy specification after several years of continuous operation. That durability translates directly into lower maintenance cost and a better return on the original investment.
Multiple Drive Options: Ball Screw, Belt-Driven, and Custom Configurations
Choosing between a ball screw linear module and a belt-driven linear module is one of the most important decisions in any motion design. Ball screw units deliver high thrust, excellent accuracy, and strong resistance to back-driving, which suits vertical axes and heavy payloads. Belt-driven units offer longer strokes, higher maximum speed, and lower cost per metre of travel, making them ideal for gantry and transfer applications. Sikete manufactures both families and can also supply gear rack drives and linear motor stages when extreme speed or unlimited stroke is required. In addition, engineers can combine drive types, add dual carriages, or integrate a brake and reducer into the same footprint. This flexibility means the linear module can be matched to the task instead of forcing the task to fit a limited catalogue.
Flexible Stroke, Load, Speed, Motor, and Mounting Customisation
Standard stroke lengths are convenient, but most real machines need something specific, and that is where custom manufacturing becomes valuable. Sikete can build a linear module to almost any practical stroke, from a few tens of millimetres up to several metres, with the screw or belt sized accordingly. Load capacity is matched by selecting the correct guide rail width, carriage type, and preload class. Speed requirements determine the lead of the screw or the pulley ratio, while duty cycle influences lubrication and cooling choices. Mounting is equally adaptable: horizontal, vertical, inverted, or multi-axis gantry arrangements are all supported with the appropriate brackets and locating features. Motors can be supplied separately or pre-mounted, and the electrical interface can be tailored to the customer's controller.
Factory-Direct Pricing, Strict Quality Control, and Fast Delivery
Buying directly from the manufacturer removes distributor mark-ups and, more importantly, removes layers of technical misunderstanding. When you discuss a linear module with Sikete, you are talking to engineers who can adjust the design, explain tolerances, and confirm feasibility before a purchase order is issued. Because the factory performs its own machining and assembly, quality problems are caught at the source rather than discovered after shipping. Standard models are usually available from stock or with short production windows, and custom units follow a clearly communicated schedule. Packaging is designed for international freight, with moisture protection, foam blocking, and reinforced cartons or crates. Combined with responsive after-sales support, this makes the total cost of ownership highly competitive.
Product Range and Technical Specifications
Sikete's catalogue is organised into clear product families so that buyers can quickly match a linear module to an application. Precision slide tables such as the PSH, PSS, PSM, and PSC series cover ball screw driven axes with different rail widths and load classes. The PBS and PBC synchronous belt slides are aimed at long-stroke, high-speed duties, while SKR linear motor stages serve ultra-dynamic and ultra-precise tasks. SHS gear rack drives extend the range to very long travel with high thrust. Detailed dimensions, load ratings, and ordering codes for all of these families are listed on the Key Products page, which is the fastest way for a design engineer to shortlist a candidate. Full category navigation is also available on the PRODUCTS page.
Typical specifications for a mid-size ball screw linear module include stroke ranges from 100 mm to 1500 mm, payload capacities from a few kilograms up to well over one hundred kilograms, and maximum speeds between 0.5 and 1.5 m/s depending on screw lead. Positioning accuracy is commonly quoted as plus or minus 0.01 mm over the full stroke, with repeatability of a few microns. Belt-driven models trade some of that accuracy for speeds up to 3 m/s and strokes beyond 3 metres, which is why they dominate transfer and gantry work. Motor compatibility covers NEMA 23 and NEMA 34 steppers, 400 W to 750 W servo motors, and integrated motor-plus-drive options that simplify wiring. Environmental versions include sealed units for dusty workshops, stainless or coated hardware for humid food environments, and low-particle configurations for cleanrooms. Every unit ships with a test report that documents the measured performance of that specific linear module.
How to Choose the Right Linear Module
Selection always begins with a clear definition of the application requirements, because no single linear module is best for everything. Start by calculating the total moving mass, including the carriage, tooling, cable chain, and the payload itself, then add a safety margin for acceleration forces. Stroke length should include the working travel plus the mechanical dead length at each end of the module. Speed and acceleration determine the required screw lead or belt ratio, and they also drive the motor sizing. Precision and repeatability requirements decide whether a ground ball screw, a rolled screw, or a belt drive is appropriate. Duty cycle, ambient temperature, and contamination level then determine lubrication, sealing, and cooling provisions.
The next step is a structured comparison of ball screw versus belt-driven linear modules. Choose a ball screw linear module when you need high thrust, vertical lift capability, fine positioning, or strong resistance to external pushing forces. Choose a belt-driven linear module when stroke is long, speed is high, and the required accuracy is in the 0.05 mm range or looser. In many machines, the correct answer is a mix: belt drives for the long transfer axis and ball screws for the precise tool axis. Mounting orientation must also be considered, because a vertical axis usually requires a brake or a self-locking screw. Finally, confirm that the chosen linear module is compatible with the controller, drive, and feedback system already used in the machine, and ask Sikete's engineers to review the load calculation before you finalise the order.
Buying Guide: Ordering from ZHEJIANG SIKETE TECHNOLOGY CO., LTD.
Requesting a quotation is straightforward, but the quality of the quotation depends entirely on the quality of the information you supply. Prepare a short technical brief covering stroke, load, speed, acceleration, accuracy, repeatability, duty cycle, mounting orientation, and the motor you intend to use. Include drawings or a photograph of the mounting interface if one already exists, and state whether the axis is horizontal, vertical, or part of a multi-axis gantry. Mention the environment, including dust, moisture, temperature, and any cleanroom classification. If you already have a target budget and delivery date, share them, because they influence which series the engineers will recommend. With this information, Sikete can return a specific model number, a performance estimate, and a firm price rather than a vague range.
OEM and ODM services extend well beyond simple configuration changes. Customers can have their own brand applied, request specific colours, specify connector types, and define cable lengths and routing. Custom carriage plates, special hole patterns, dual-carriage arrangements, and integrated drag chains are all common modifications. For higher volumes, Sikete can develop a dedicated linear module platform that reduces part count and cost while preserving the required performance. Sample testing is encouraged before mass production, and prototypes can usually be produced quickly to validate the design in the real machine. Once approved, production, inspection, and packaging procedures are locked, so repeat orders match the original sample exactly. Communication throughout the project is handled by an assigned engineer rather than a rotating pool of sales staff.
Lead times depend on whether the item is a standard model or a custom build, and both are communicated clearly before the order is confirmed. Standard linear module sizes are often available from stock, while custom units typically require a few weeks for machining, assembly, and testing. Packaging uses moisture barrier bags, custom foam, and reinforced export cartons or wooden crates for longer units. Shipping can be arranged by express, air freight, or sea freight, and the documentation needed for customs clearance is prepared accurately. Warranty terms and spare parts availability are documented, and technical support continues after delivery. If anything is unclear at any stage of the process, the team can be reached directly through the CONTACT page, which also collects the most frequently asked questions from buyers.
Applications Across Industries
Linear modules appear in an enormous range of machinery, and the requirements differ significantly from sector to sector. In CNC machining and engraving, a rigid ball screw linear module carries the spindle or the worktable with high accuracy and good resistance to cutting forces. In robotics and pick-and-place systems, lightweight belt-driven axes position a gripper quickly across a wide working area. Packaging machinery relies on linear modules for sealing, labelling, filling, and carton handling, where speed and reliability matter more than micron-level precision. Laser cutting and marking equipment uses precision modules to keep the focal point exactly on the material being processed. Testing and inspection equipment often requires the smoothest, quietest motion available, which is where linear motor stages and high-grade ball screws excel. Photographs and descriptions of real installations can be reviewed on the Application Case page.
The measurable benefits reported by customers usually fall into three categories: throughput, quality, and maintenance cost. Faster settling times and higher acceleration shorten each cycle, which raises output without buying new machinery. Tighter repeatability reduces scrap and rework, especially in dispensing and assembly operations where a fraction of a millimetre changes the result. Longer service intervals reduce unplanned downtime and the labour required to keep equipment running. Because a Sikete linear module is a sealed, factory-tested assembly, commissioning is also faster than building a motion axis from separate rails, screws, and bearing blocks. Machine builders can therefore shorten their own delivery schedules while improving the reliability they offer to their customers. Video walkthroughs of products and factory facilities are available on the VIDEO page for those who want to see the hardware before ordering.
Maintenance Tips for Long-Term Performance
Even a well-engineered linear module benefits from a simple, disciplined maintenance routine. Lubrication is the most important task: ball screw units should be greased at the interval recommended in the manual, using the specified lithium or PTFE-based lubricant. Belt-driven modules require checking belt tension periodically, since a slack belt causes lost motion and a belt that is too tight accelerates bearing wear. Wipe the guide rail and screw clean before applying new grease, because pushing contaminated lubricant back into the carriage causes rapid damage. Check the wipers and seals for cuts or hardening, and replace them before dust reaches the rolling elements. Inspect mounting bolts and coupling clamps for looseness, especially in machines that experience high vibration or thermal cycling. Finally, listen to the axis during operation, since a change in sound is often the first sign of a developing problem.
Several mistakes appear again and again in the field and are worth avoiding deliberately. Over-greasing is common and can cause churning, heat build-up, and premature seal failure, so follow the recommended quantity rather than adding more for safety. Ignoring parallel alignment between multiple axes on a gantry will load the carriages unevenly and shorten their life dramatically. Running a linear module beyond its rated moment load, particularly with an offset tool, causes deflection that no amount of re-lubrication can fix. Using the wrong lubricant or mixing incompatible greases can thicken the original charge and increase drag. Skipping the break-in period and immediately running at maximum speed may damage the ball nut or belt. Recording service dates and observations turns maintenance from guesswork into a predictable, planned activity.

Frequently Asked Questions (FAQ)
What is a linear module and how is it different from a linear actuator?
A linear module is a complete, sealed motion assembly that combines a structural profile, a precision guide, a drive element such as a ball screw or belt, and a motor mounting interface. A linear actuator often refers to a simpler device, frequently with a rod or a short-stroke mechanism, used for pushing or lifting rather than for accurate positioning. In practice, a precision linear module is specified when repeatability, speed, and load capacity must all be controlled at the same time. Sikete builds linear modules designed specifically for continuous industrial duty.
What is the typical lead time for a Sikete linear module?
Standard linear module sizes are frequently available from stock or within a short production window of roughly one to two weeks. Customised units that require special stroke lengths, machining, or motor integration usually take several weeks depending on complexity and order quantity. The exact schedule is confirmed in writing before production begins, so there are no surprises. Shipping time by express, air, or sea is then added to the production lead time.
Can Zhejiang Sikete Technology customize stroke length and load capacity?
Yes, customisation is one of the company's core strengths as a linear module manufacturer. Stroke lengths can range from a few tens of millimetres up to several metres, with the screw or belt selected to suit the required speed and thrust. Load capacity is matched by choosing the appropriate rail width, carriage type, and preload class. Custom mounting plates, dual carriages, and special hole patterns are also available.
Which motor is best for my linear module application?
Stepper motors are economical and work well for moderate loads, moderate speeds, and applications where continuous position feedback is not critical. Servo motors are the better choice for high dynamic performance, heavy payloads, and applications requiring tight velocity control. Integrated motor-and-drive units simplify wiring and reduce panel space, which is valuable in compact machines. Sikete can supply the module with the motor pre-mounted and aligned, or as a bare unit for your own motor.
Should I choose a ball screw or a belt-driven linear module?
Choose a ball screw linear module when you need high thrust, fine positioning accuracy, vertical lift capability, or strong resistance to external forces. Choose a belt-driven linear module when the stroke is long, the speed is high, and the required accuracy is in the 0.05 mm range or looser. Many machines use both types, with belts for transfer axes and ball screws for precise tool axes. Sikete's engineers can review your load and speed data and recommend the right option.
How do I get factory-direct pricing for a linear module?
Factory-direct pricing is available by contacting Zhejiang Sikete Technology directly with a clear technical brief. Provide the stroke, load, speed, accuracy, duty cycle, mounting orientation, and preferred motor, and the engineering team will return a specific model recommendation with a firm quotation. Buying directly removes distributor mark-ups and shortens the technical feedback loop. Volume discounts and OEM arrangements can also be discussed at the same time.
Can I order a sample linear module before placing a mass-production order?
Yes, sample testing is encouraged and is a normal part of the process for new customers and new designs. A prototype allows your team to verify accuracy, speed, vibration, and mounting compatibility inside the real machine before committing to volume. Once the sample is approved, production procedures and inspection criteria are locked so that repeat orders match exactly. Feedback from the sample stage is also used to refine any custom features.
What maintenance does a linear module require?
Regular lubrication is the single most important maintenance task, and the correct grease should be applied at the interval stated in the manual. Clean the rail and screw before adding new lubricant so that contamination is not pushed into the carriage. Check belt tension on belt-driven units and inspect wipers and seals for wear. Re-tighten mounting bolts periodically, particularly on machines with high vibration, and listen for changes in operating noise.
What warranty and after-sales support do Sikete linear modules include?
Every unit is inspected and tested before shipment, and warranty terms are documented as part of the order. Spare parts such as belts, ball nuts, and wipers remain available so that a linear module can be serviced rather than replaced. Technical support continues after delivery, including help with commissioning, troubleshooting, and selecting replacement components. Buyers can reach the team through the official CONTACT page for any service request.
Are Sikete linear modules suitable for cleanroom or harsh environments?
Sikete offers application-specific versions with enhanced sealing, stainless or coated hardware, and low-particle lubrication for cleanroom use. For dusty or humid workshops, wipers and sealed carriages prevent contamination from reaching the rolling elements. In food-processing areas, corrosion-resistant finishes and washdown-friendly designs can be specified. The environment should always be described in the enquiry so that the correct protection level is built into the linear module from the start.
