Our HSR GK Series LM Guides comprises of THK’s oldest yet one of its most successful conventional Linear Bearing family, dating back to the early 1980’s. Blocks and rails can be purchased individually, with the freedom to mix and match, quickly and easily. Our latest addition of the HSR Series has been Redesigned for even higher performance.
Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and endplates incorporated in the LM block allow the balls to circulate. Since retainer plates hold the balls, they do not fall off even if the LM rail is pulled out (except certain models currently not featured as standard stock, i.e. HSR 8, 10 and 12).
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 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. With the low sectional height and the high rigidity design of the LM block, this model achieves highly ac- curate and stable straight motion.
[4-way Equal Load]
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 the four directions (radial, reverse radial and lateral directions), enabling the LM Guide to be used in all orientations and in extensive applications.
[High Rigidity Type]
Since balls are arranged in four rows in a well-balanced manner, a large preload can be applied and the rigidity in four directions can easily be increased.
[Self-adjustment Capability]
The self-adjustment capability through front-to-front configuration of THK’s unique circular-arc grooves (DF set) enables a mounting error to be absorbed even under a preload, thus to achieve highly accurate, smooth straight motion.
[High Durability]
Even under a preload or excessive biased load, differential slip of balls does not occur. As a result, smooth motion, high wear resistance, and long-term maintenance of accuracy are achieved.
[Stainless Steel Type also Available]
A special type which LM block, LM rail and balls are made of stainless steel is
also available on request on a Made to Order Basis.
The flange of the LM block has tapped holes. Can be mounted from the top or the bottom. Large volume stock available from our warehouse.
Prices are available on request.
The LM block has the same cross-sectional shape as model HSR-C, but has a longer overall LM Block length (L) and a greater rated load.

Having a smaller LM block width (W) and tapped holes, this model is optimal for compact design. Large volume stock available from our warehouse.
