Rack and Pinion Linear Module – VG22
Long Travel · Heavy Duty Load · Precision Motion Platform
Ⅰ. Product Overview
The VG22 Rack and Pinion Linear Module from W-Robot is engineered for automation systems requiring extended stroke lengths, high-load handling, and precise linear positioning. Employing a robust rack-and-pinion transmission mechanism, the VG22 delivers consistent thrust, minimal backlash and high dynamic response — the ideal choice for gantry systems, large-format pick-and-place machines, heavy logistic transfer lines and other demanding industrial motion applications.
Designed with a rigid aluminum alloy frame, precision guide rails and modular structure, the VG22 supports horizontal, vertical or gantry installations and enables seamless integration in multi-axis motion platforms.
Ⅱ. Technical Features
Heavy-duty rack & pinion drive: high thrust, long stroke capability, excellent dynamic performance.
Extended travel support: configurable stroke lengths up to multiple meters for large-layout automation systems.
Rigid structural frame: high-strength aluminum body and reinforced guide infrastructure ensure stable motion under load.
Minimal mechanical backlash: thanks to precision pinion and rack design, offering high repeatability.
Versatile mounting: horizontal, vertical or gantry orientation supported; compatible with servo & stepper systems.
Modular integration: supports X/Y/Z multi-axis layout or tandem carriages for higher payload.
Low maintenance: simpler transmission path compared to screw or belt systems, reducing wear and downtime.
Ⅲ. Application Fields
The VG22 module is particularly well-suited for scenarios such as:
Large-format gantry systems for material handling and assembly.
High-throughput loading/unloading lines in CNC or stamping environments.
Precision inspection and measurement machines with long travel spans.
Logistics transfer modules, palletising systems and heavy payload motion.
Multi-axis robotic systems handling large parts or assemblies.
Ⅳ. Model Selection & Customization
W-Robot offers comprehensive customization options for the VG series to ensure the VG22 meets your automation requirement:
Adjustable stroke length, rack & pinion gear ratios, carriage load capacity.
Motor flange and drive interface customization (servo, stepper, integrated motor) to match control systems.
Support for multi-axis configurations (X/Y/Z) or tandem carriage for increased load/rigidity.
Optional protective covers, dust-proofing, lubrication ports for harsh environments.
2D/3D CAD models and full technical documentation are available on request.
Ⅴ. Product Advantages
Long travel distance with heavy load capacity in one compact module.
Rack & pinion drive offers minimal backlash, high speed and long service life.
Modular design simplifies integration into large systems or multi-axis layouts.
Reduced maintenance requirement compared to long-travel screw or belt systems.
Excellent cost-performance for heavy duty automation solutions.
Ⅵ. Installation & Maintenance
Ensure mounting surface is flat, rigid and properly aligned before installation.
Confirm correct rack-pinion engagement and alignment to minimize backlash and wear.
Keep guide rails, rack teeth and carriage surfaces clean; inspect periodically for wear (recommended every 6–12 months).
Avoid excessive side loads, shocks or torque beyond rated specifications.
Secure all fasteners to the manufacturer’s specified torque values.
In high-dust or high-humidity environments consider protective covers or sealed carriages.

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.
