Features
Structure and Features
Balls roll in four rows of raceways precision-ground on the LM rail and LM block and are circulated by ball cages and end plates incorporated in the LM block. Each row of balls is placed at a contact angle of 45° so that the load ratings applied to the LM block are uniform in the four directions (radial, reverse-radial, and lateral directions), enabling the LM Guide to be used in all orientations. In addition, the LM block can receive a well-balanced preload, increasing the rigidity in the four directions while maintaining a constant, low friction coefficient.
Four-Way Equal Load
Each row of balls is placed at a contact angle of 45° so that the load ratings applied to the LM block are uniform in the four directions (radial, reverse-radial, and lateral directions), enabling the LM Guide to be used in all orientations and in extensive applications.
Self-Adjustment Capability
The self-adjustment capability of the front-to-front configuration of THK’s unique circular-arc grooves (DF set) enables mounting error to be absorbed even under a preload, thus achieving highly accurate and smooth linear motion.
Global Standard Size
SHS is designed to have dimensions nearly equal to the Full-Ball LM Guide Model HSR, the de facto global standard with which THK pioneered the LM System.
Stainless Steel Type also Available
A special type whose LM block, LM rail, and balls are made of stainless steel is also available. Applicable only to models 15 through 25.
