THK US Universal Series

The THK Universal Series US / USW is a robust electric linear actuator designed for long-stroke, high-speed motion and heavy load transport. This series combines a ball screw drive with precision LM Guide motion to deliver industry-leading service life, with many models capable of up to 20,000 km running life under maximum load.

Long-term maintenance-free operation is supported by caged ball LM Guides and QZ lubricators that supply optimized lubricant to the ball screw, reducing service requirements. A smart structure with built-in sensors and easy assembly features such as dowel pin holes and elongated base holes streamline installation, while a versatile lineup of stroke lengths (100 mm to 1,700 mm) and ball screw leads allows selection tailored to your application needs. The Universal Series is ideal for automation systems where long travel, heavy payloads, high speed, and reliable performance are essential.
