Caged Ball LM Guide Cross LM Guide Model SCR

Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and ball cages and end plates incorporated in the LM block allow the balls to circulate. This LM Guide has two rails intersecting at right angles integrated back-to-back into a single block with the same internal structure as the proven Caged Ball LM Guide Model SHS. Because an orthogonal LM System can be achieved with the Model SCR alone, conventional saddles are no longer necessary, enabling simplified X-Y motion and compact structure.

4-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.

High Rigidity

Since balls are well balanced in four rows, this model is able to withstand moments, and it achieves smooth linear motion even when a preload is applied to increase the rigidity. Since the rigidity of the LM block is higher than that of a combination of two LM blocks of the conventional type secured together back-to-back with bolts, this model is optimal for building an X-Y table that requires high rigidity.
