1. Product Overview

The ZR-VS6-20 Linear Rotary Actuator from W-Robot is a high-precision integrated module that combines linear motion and rotational motion within a compact structure. It is designed for high-speed, high-accuracy automation systems such as pick-and-place devices, assembly machines, testing stations, and other industrial automation equipment requiring synchronized rotation and linear movement.

2. Key Features

Integrated Design: Combines linear and rotary motion in one compact unit, simplifying installation and system layout.

High Precision Control: Utilizes advanced servo motor technology for accurate motion synchronization.

Compact and Lightweight: Optimized structure for space-saving applications, ideal for multi-axis robotic systems.

Durable and Stable: Built with high-strength materials and precision bearings for long service life.

Customizable Options: Supports customization in stroke length, torque, and mounting interface.

Maintenance-Free Operation: Designed with sealed internal components to minimize maintenance requirements.

3. Technical Specifications

Parameter	Specification

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.
