Bearing Engineers Inc. THK SHS LM Guide

Avantages of Caged Ball Technology

High Speed Performance
Low Noise Design
Long-term, maintenance-free operation
Reduction inrolling resistance variation

SHS features

Four way equal load rating
This LM system can be used for different applications in any position because each row of balls is arranged at a 45-degree contact angle, so that the same load rating is applied to the LM block in four directions (radial, reverse radial, and lateral directions).

Automatic adjustment capability
Because of the automatic adjustment capability of THK's unique circular arc groove design (face to face/DF), mounting misalignment can be eliminated, even when a preload is applied. As a result, precise, smooth linear movement is achieved.

Global standard dimensions
The design of type SHS conforms to that of type HSR, which THK developed as a pioneer of linear motion systems. This design has virtually become the global standard. The load rating and rigidity are equivalent to those of the type HSR.

Low center of gravity and high rigidity
The rail section has a compact design, resulting in a low center of gravity and high rigidity.
