### **Linear Module Product Introduction**

#### **1. Product Overview: What is a Linear Module?**

A linear module, also known as a linear slide, electric slide, or actuator module, is an automated unit that integrates **transmission, guidance, and drive** into a single package. Driven by an electric motor, it precisely converts rotary motion into linear motion, enabling **precise positioning, handling, and reciprocating movement** of a load.

As a core component in automation equipment, the linear module is recognized as a modern solution replacing traditional "cylinder + guide rail" setups. Known for its **high integration, high precision, high rigidity, and ease of installation and maintenance**, it is often hailed as the "robotic arm of the industrial field."

#### **2. Core Advantages & Value**

*   **High Precision & High Rigidity:** Utilizes precision ball screws/guide rails or high-performance synchronous belts, ensuring smooth operation, high repeatability, and the ability to withstand multi-directional loads.
*   **High Speed & High Efficiency:** Especially belt-driven modules, capable of achieving much higher speeds than traditional cylinders, significantly improving equipment cycle times and production efficiency.
*   **Simplified Design & Space Saving:** The modular design greatly simplifies mechanical structural design, saves equipment installation space, and shortens R&D cycles.
*   **Easy Installation & Simple Maintenance:** Pre-adjusted and tested before shipment, users can typically get started with simple installation and connection of power and signals, drastically reducing installation and maintenance costs.
*   **Long Service Life & High Reliability:** Core components are made from high-quality alloy steel and high-performance engineering plastics. Under normal use and maintenance, service life can reach tens of thousands of hours.
*   **High Flexibility & Customization:** Supports multi-axis combinations for easily building XYZ Cartesian robots, gantry systems, etc. Offers various customization options like stroke, motor type, and feedback systems.

#### **3. Main Product Types**

Based on the transmission method, linear modules are primarily divided into two main categories:

**1. Ball Screw Linear Modules**
*   **Working Principle:** A servo or stepper motor rotates the ball screw. Through the recirculating ball mechanism, the rotary force is converted into linear thrust on the slide.
*   **Key Features:**
    *   **Ultra-High Precision:** Repeatability can reach ±0.01mm or higher.
    *   **High Thrust:** High transmission efficiency, capable of handling heavier loads.
    *   **High Rigidity:** Good self-locking capability and stable positioning.
*   **Ideal Applications:** Suitable for applications demanding high precision and load capacity.
    *   **Typical Uses:** Precision inspection equipment, semiconductor packaging, dispensing machines, PCB drilling, precision assembly, medical devices.

**2. Synchronous Belt Linear Modules**
*   **Working Principle:** A servo or stepper motor drives the drive pulley, which transmits power to the idler pulley via a synchronous belt, moving the slide linearly along the guide rails.
*   **Key Features:**
    *   **Ultra-High Speed:** Maximum speeds can reach 3-5 m/s, significantly higher than screw modules.
    *   **Long Stroke:** Can achieve very long strokes (over 10 meters) without splicing, offering clear cost advantages for long travels.
    *   **Low Noise & Clean Operation:** Relatively low operating noise and no metallic wear debris.
*   **Ideal Applications:** Suitable for applications where speed and long travel are prioritized.
    *   **Typical Uses:** Laser cutting/marking, material handling and sorting, spraying, packaging, automated production lines, 3D printing.

**(Optional) 3. Rack and Pinion Linear Modules**
*   **Description:** Suitable for **very long strokes and ultra-heavy loads** in heavy-duty industrial applications, such as large gantry machining centers and material handling systems.

#### **4. Detailed Technical Parameters**

Consider these core parameters during selection:

| Parameter Category | Specific Parameters | Description |

| **Core Performance** | Repeatability | Consistency of returning to the same position; a key accuracy indicator. |
| | Positioning Accuracy | Overall deviation between actual and commanded position. |
| | Maximum Load | Maximum effective load the slide can handle at its center. |
| | Maximum Speed / Acceleration | Determines equipment motion efficiency and cycle time. |
| **Structural Dimensions** | Effective Stroke | Maximum linear travel distance of the slide. |
| | Module Width / Height | Determines the module's footprint and required installation space. |
| **Drive & Configuration** | Drive Method | Screw (requires lead specification), Belt (requires pitch/belt width specification). |
| | Motor Type | Servo motor, Stepper motor, Brushless DC motor, etc. |
| | Guide Rail / Block Grade | Determines module rigidity, precision, and lifespan. |
| | Guidance Type | Typically precision linear guide rails or cross roller guides. |
| **Auxiliary Features** | Limit Switches | Mechanical or photoelectric, used for safe travel limitation. |
| | Home Sensor | Used to find the system's mechanical home position. |
| | Brake Unit | Prevents load drop after power loss (especially in vertical installations). |
| | Protection Rating | e.g., IP54, IP65, determines dust and water resistance. |
