THK SHS LM Guides

THK Global Standard size LM guide model SHS

Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and ball cages and endplates incorporated in the LM block allow the balls to circulate. 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, SHS achieves highly accurate and stable linear motion.

Model SHS has the same dimensions as model HSR, which is the de facto global standard full-ball LM guide, and can be mounted in any orientation since it is 4-way equal load type.

Major applications: Machining center / NC lathe / drilling machine / electric discharge machine / conveyance system.
