By incorporating an LM Guide within its rectilinear guide, the ES provides both compactness and reliability.

Compact and reliable

The use of LM Guides reduces the number of components required, making the ES available at a reasonable cost.

Reasonably priced

The ES incorporates the model SRS LM Guide, equipped with ball retainers, as well as Lubricator QZ, for optimal

ball-screw lubrication. The combined effect provides for long-term maintenance-free operation.

Long-term maintenance-free operation

The service life of the LM Guide and ball screw can be calculated based on usage conditions.

Contact THK for details.
