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
models 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.
