Linear Module And Ball Screw Linear Actuator

Linear module (linear module/linear sliding table) is an automated motion unit that integrates linear guides, ball screws (or synchronous belts), and drive units, achieving high-precision linear or curved motion through modular design. The core components include: Transmission components: ball screw , synchronous belt (suitable for long stroke) or gear rack (heavy-duty scenario); Guiding components: steel linear guide rail; Drive unit: servo motor, stepper motor or cylinder.

  • Product Features

    Easy to design and install

    Small size and light weight

    high-precision

    rigidity

    Fully equipped

    Optimal design

  • Performance Advantages

    1. High speed response and stability

    Adopting a dual axis guide rail and chrome plated axis design, it has the characteristics of low friction and high rigidity, supports frequent start stop and smooth operation, and has lower noise than traditional transmission devices.

    2、 Protection and Durability

    Fully enclosed dust-proof technology, the new module uses sealing tape and contact components to effectively prevent external dust from entering the interior of the base, and automatically cleans up attached dust during movement, extending the service life of the equipment

    3. Corrosion and rust resistance characteristics

    The aluminum alloy material slider and axis support seat are treated with anodizing, and the axis is plated with hard chromium, which has both rust prevention and corrosion resistance, and is suitable for harsh industrial environments.

    4. Customized modular design

    The slide rail and slider can be supplied separately, and the worn parts support complete interchangeability, reducing maintenance complexity and costs in the later stage.

    5. High cost-effectiveness

    Compared to linear motors, linear modules adopt standardized structural design, with lower production costs, and can expand load capacity through rigid guide rails, covering light to heavy load scenarios.

  • Product Application

    CNC machining equipment

    Robot Integration

    AOI optical inspection equipment

    Automatic soldering machine, surface mount machine

    New energy and power equipment

    medical equipment

    Automobile and Heavy Equipment Manufacturing

  • Product Selection

    1、 Core performance parameters

    Load: dynamic load, static load

    Maximum speed: Synchronous belt module can reach 5m/s (such as GTB series), ball screw module is usually ≤ 1.5m/s

    Effective travel: Requires 10-15% over travel protection distance to avoid mechanical limit collisions

    2‌.、Body size and material

    Module width: determines load capacity

    Installation length: needs to match effective travel and mechanical limit space

    Sliding block type: flange type (flat width design) or square type (high rigidity design)

    Protection level: Fully enclosed module>Semi enclosed module>Open module

    3、 Environmental adaptation parameters

    Temperature compensation: Precision scenes require the configuration of grinding grade screw rods

    Corrosion resistance: anodized aluminum+chrome plated shaft, suitable for acidic and alkaline environments

    Dustproof design: stainless steel sealing tape+automatic dust cleaning structure (suitable for dust-free workshops)
