Product Family — What Sets Each Type Apart

Understanding the distinctions across a broad linear module product family helps engineers select the right platform for their specific environment, load, accuracy, and travel requirements. Here is a clear breakdown of each module type and what differentiates it.

1. Guide Rail Built-in Linear Actuator

The foundational platform of the product family. The linear guide rail is integrated directly inside the module housing, protecting it from external contact while providing a compact, clean exterior profile. The built-in rail delivers high rigidity, smooth carriage motion, and consistent load capacity across the full stroke. Available in aluminum alloy and steel versions, these modules suit general industrial automation, pick-and-place systems, and assembly line positioning where a clean, space-efficient form factor is the priority.

2. Screw Linear Module for General Environment

A standard ball screw or lead screw driven module designed for typical indoor factory conditions — moderate dust, ambient temperature, and no liquid exposure. The screw drive delivers precise, repeatable positioning suitable for material handling, dispensing, and light CNC auxiliary axis applications. No additional sealing or protection is incorporated, keeping unit cost low for applications where environmental exposure is not a concern.

3. Long Stroke Screw Linear Module for General Environment

Functionally identical to the standard screw module but engineered specifically for extended travel lengths — typically 1,000 mm to 4,000 mm or beyond. Longer screw spans require careful management of critical speed and screw deflection, so these modules incorporate larger diameter screws, optimized end-support bearing configurations, and in some cases intermediate screw supports to maintain accuracy and dynamic stability across the full extended stroke.

4. Timing Belt Linear Module for General Environment

Replaces the screw drive with a recirculating timing belt and pulley system. The belt drive decouples linear speed from screw rotational dynamics, enabling significantly higher traverse speeds — typically 500 to 3,000 mm/s — at the cost of reduced positioning accuracy compared to screw-driven modules. Ideal for high-speed gantry systems, label applicators, and long-travel transport axes where throughput matters more than micron-level precision.

5. Lead Screw Linear Module for Dust-proof Environment

A lead screw driven module with enhanced dust exclusion measures — typically full-length cover strips, carriage wiper seals, and sealed end caps — designed for environments with airborne particulates, wood dust, plastic swarf, or powder contamination. The self-locking lead screw provides inherent vertical axis holding without brake power, making this module well suited for dusty woodworking, stone cutting, and powder handling automation.

6. Timing Belt Linear Module for Dust-proof Environment

Combines the high-speed capability of belt drive with dust-exclusion sealing — cover strips and carriage wipers prevent particulate ingress into the guide rail and bearing zone. This module targets high-speed applications in moderately contaminated environments: cardboard packaging lines, textile machinery, and printing equipment where speed is essential but ambient dust levels demand basic protection beyond a standard open module.

7. Bellows Cover Waterproof Lead Screw Linear Module

Adds full-length accordion bellows over the lead screw and rail exposure zones, providing robust protection against water splash, coolant mist, and heavy chip or swarf accumulation. The bellows physically enclose the vulnerable screw and guide surfaces at all carriage positions. Suited for machine tool peripherals, wet grinding stations, and washdown-adjacent automation where water and debris contact is frequent.

8. Bellows Cover Waterproof Timing Belt Linear Actuator

Applies the same bellows protection concept to a belt-driven module, combining high traverse speed with physical exclusion of water and contaminants. This configuration serves high-speed automation in wet or contaminated environments — vehicle wash equipment, food conveyor diverters, and outdoor portal systems — where neither belt modules nor standard waterproof modules alone would suffice.

9. European Dustproof Timing Belt Module

Follows European machine design standards and dimensional conventions — typically DIN/ISO compatible mounting interfaces, metric fastener patterns, and integrated T-slot profiles compatible with European aluminum profile systems. Dust exclusion sealing meets European machinery directive requirements. Preferred by OEMs supplying into European markets or integrating with Bosch Rexroth, Item, or Minitec profile-based machine frames.

10. Steel Type: Guide Rail Built-in Linear Actuator

The heavy-duty variant of the guide rail built-in platform, fabricating the module body from structural steel rather than aluminum alloy. The steel construction delivers substantially higher rigidity, greater load capacity, and superior resistance to deformation under eccentric or cantilevered loads — critical for large-format CNC auxiliary axes, heavy workpiece transfer systems, and high-force pressing or clamping applications where aluminum housings would flex unacceptably under load.

Quick Selection Summary
