Rack and Pinion Linear Module – VG27
High Load · Long Stroke · Precision Linear Drive
Ⅰ. Product Overview
The VG27 Rack and Pinion Linear Module from W-Robot is an advanced motion unit engineered for high-performance linear positioning applications that demand extended travel, heavy payloads, and perfect repeatability. The rack-and-pinion drive mechanism delivers both high thrust and longer stroke capacity with minimal backlash compared to conventional screw or belt-based systems.
Built with a rigid structural frame and precision guide rails, the VG27 module is ideal for use in gantry systems, heavy-duty transfer stations, large-format pick-and-place machines and other demanding automation setups.
Ⅱ. Technical Features
Heavy-duty rack & pinion drive unit: designed for high thrust, long travel and stable dynamics.
Long-stroke capability: supports extended travel lengths customized per system layout.
High structural rigidity: optimized aluminum alloy body and reinforced guide design ensure stable motion under load.
Minimal mechanical backlash and high repeatability (approx. ±0.05 mm) for precision applications. W-Robot
Flexible installation: horizontal, vertical or gantry orientation supported; compatible with Servo/Stepper drives.
Modular design allows integration into single‐axis, multi‐axis or XY/Z gantry setups.
Low-maintenance operation: fewer wearing elements compared to long-travel screws, simpler upkeep.
Ⅲ. Application Fields
The VG27 module is tailored for industrial automation applications such as:
Large gantry systems for material handling or machining
Heavy part transfer lines and palletising equipment
Precision inspection systems where long travel and accuracy are essential
Multi-axis robotic axes handling large components or assemblies
Automated logistics, loading/unloading, and large format assembly lines
Ⅳ. Model Selection & Customization
W-Robot provides broad customization services for the VG series to match specific system needs:
Adjustable stroke length, rack pitch, pinion ratio and carriage preload
Motor mount customization for Servo, Stepper or Integrated Motor types
Multi-axis configurations (X/Y/Z) or tandem carriages for higher load capacity
Environmental adaptations: dust-proof covers, sealed guides, special coatings
2D/3D CAD models and full technical documentation available on request
Ⅴ. Product Advantages
Large travel distance with high load capacity in one module
Rack & pinion drive offers minimal backlash and high repeatability
Robust structure ensures long-term stability and reliability
Simplified maintenance and enhanced lifecycle compared to long-travel screws
Easy integration into multi-axis systems or large format machines
Excellent cost-performance ratio for heavy duty automation platforms
Ⅵ. Installation & Maintenance
Install on a flat, rigid base to ensure alignment and accuracy.
Confirm proper rack-pinion engagement and alignment during installation.
Regularly inspect guide rails, rack teeth and carriage surfaces for debris or wear.
Performance check every 6–12 months recommended under heavy-duty use.
Avoid high side-loads or shock beyond rated specifications; tighten fasteners to specified torque.
For dusty or harsh environments consider dust covers or sealed variations.

FAQ

Listed below are answers to our most commonly asked questions. Don't see your question?Contact our customer service team. We would be glad to assist you.

What are the future development trends of linear modules and linear motors?

In the future, linear modules and linear motors will develop towards higher precision, higher speed, smaller size, intelligence, and integration with other advanced technologies (such as artificial intelligence and the Internet of Things).

What parameters need to be provided for customized linear motors?

It is necessary to provide detailed parameters such as load weight, stroke, speed, acceleration, accuracy requirements, installation method, and operating environment so that the manufacturer can design and manufacture a linear motor that meets the requirements.

How long is the customization cycle of linear modules?

The customization cycle depends on the complexity of the customization and the manufacturer's production capacity, generally about 1-4 weeks. The specific time can be determined by communicating with the manufacturer.

Can linear motors be upgraded?

The performance of linear motors can be improved by upgrading them with high-performance drives, optimizing control system parameters, and improving heat dissipation structures.

Is it easy to upgrade the linear module?

It is relatively easy to upgrade the motor, control system, guide rail and other components of the linear module according to actual needs to improve its performance and accuracy.

What is the after-sales maintenance service of linear motors?

Regular manufacturers usually provide comprehensive after-sales maintenance services, including fault diagnosis, maintenance guidance, parts replacement, etc., but the response speed and quality of after-sales maintenance services may vary from manufacturer to manufacturer.

What is the warranty period for linear modules?

The warranty period of linear modules from different manufacturers varies, generally around 1-2 years. The specific warranty period can be confirmed with the manufacturer at the time of purchase.

What should we pay attention to when integrating linear motors with other equipment?

Attention should be paid to issues such as interface compatibility, signal matching, control logic coordination, and installation space and layout between devices to ensure that the devices can work together.

Can the linear module be integrated with other equipment?

Absolutely. Linear modules can be integrated with other devices such as robots, sensors, and vision systems to build more complex and intelligent automated production lines.

What kind of control system do linear motors require?

Linear motors typically require a high-performance motion control system that can achieve precise position control, speed control, and thrust control, such as a dedicated linear motor drive with a motion control card or a high-end PLC.
