LM Guides - Block Only, SR Model.

Volume Discount

THK

MISUMI stocks Individual linear motion guide blocks from the THK LM guide SR series for quick and easy interchangeability, ensuring problem free maintenance and short down times.

[Features]
•Balls travel in four precision-ground raceways on an LM rail through the LM block, and endplates incorporated in the LM block.
•Each row of balls is placed at a contact angle of 45°so that the rated loads applied to the LM block are uniform in all four directions (radial, reverse-radial and lateral directions) for a constant low friction coefficient, and increased rigidity.
•Blocks self-adjust enabling mounting error to be absorbed, even under a preload, for highly accurate, smooth linear motion.
