The unique roller-holding mechanism of the Roller Cage type R with a shortened roller pitch enables the realization of an increased effective contact length for rollers. Designed by combining, the Roller Cage and dedicated Rail type V, which is precision-ground after receiving special heat treatment, the Cross Roller Guide is a highly rigid, high-precision, compact, finite linear motion system. The Ball Guide (VB type) is a type of Cross Roller Guide in which the rollers are replaced with balls.
