THK LM Guide SCR

Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and ball cagesand endplates incorporated in the LM block allow the balls to circulate.This model is an integral type of Caged Ball LM Guide that squares an internal structure similar tomodel SHS, which has a proven track record and is highly reliable, with another and uses two LMrails in combination. Since an orthogonal LM system can be achieved with model SCR alone, aconventionally required saddle is no longer necessary, the structure for X-Y motion can be simplifi edand the whole system can be downsized.[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 blockare uniform in the four directions (radial, reverse radial and lateral directions), enabling the LMGuide to be used in all orientations and in extensive applications.[High Rigidity]Since balls are arranged in four rows in a well-balanced manner, this model is stiff against a moment,and smooth straight motion is ensured even 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 conventionaltype secured together back-to-back with bolts, this model is optimal for building an X-Ytable that requires a high rigidity.[Compact]This model is an integral type of Caged Ball LM Guide that squares an internal structure similar tomodel SHS, which has a proven track record and is highly reliable, with another and uses two LMrails in combination. Since an orthogonal LM Guide can be achieved with model SCR alone, a conventionallyrequired saddle is no longer necessary, the structure for X-Y motion can be simplifi edand the whole system can be downsized.
