SDH Series Built-In Ball Screw Linear Actuator

SDH Series Built-In Ball Screw Linear Actuator is designed for automated production systems that require compact structure, guided stability and repeatable positioning.Its built-in actuator structure combines ball screw transmission with linear guide support for compact, stable and repeatable precision motion.As an Automation Ball Screw Linear Module, SDH Series is suitable for precision assembly, electronics manufacturing, battery equipment, testing systems, inspection devices and compact positioning units. It is a better choice than a belt driven actuator when the application requires rigidity, stable load support and accurate movement in a limited installation space.

SDH Series Built-In Ball Screw Linear Actuator Frequently Asked Questions

01

What’s the difference between a ball screw, belt, and rack & pinion...

Ball screw modules offer high precision and rigidity for accurate positioning. 

Belt modules are ideal for high-speed, long-travel motion. 

Rack & pinion modules handle heavy loads and extra-long strokes.

02

How do I select the right linear module?

Selection depends on load, travel distance, speed, installation direction, and precision requirements. Our engineers can assist with model selection if you share your application data.

03

Can the module be mounted vertically?

 Yes, but vertical installation requires a brake motor or mechanical lock to prevent gravity drop.

04

What is the repeat positioning accuracy?

Ball screw type: ±0.01 mm; Belt type: ±0.05 mm; Rack & pinion type: ±0.1 mm.

05

Do the modules require maintenance?

Yes. Apply grease every 500 operating hours or 3 months and keep the guideways clean.

06

Which motor brands are compatible?

 Compatible with Delta, Mitsubishi, Panasonic,Yaskawa, Inovance, and most standard servo motors.

07

Can you provide custom stroke or dust-proof options?

Yes. Customized stroke lengths, dust covers, and mounting interfaces are available upon request.

08

What is a clean room belt driven linear actuator?

A clean room belt driven linear actuator is a linear motion module that uses a timing belt and linear guide structure to move a carriage along a straight axis. The MTG Series is designed for clean room and precision automation applications requiring high speed, long stroke, low noise and stable operation.
