Face Mount Cross Roller Bearings - RA, RB Series

RB series is the basic design of high precision cross roller ring. It has two split outer rings and one integrated inner ring. Besides, RA series is the thin wall type of face mount crossed roller bearing, its design is based on the RB series, but it has the lighter and more compact construction. Therefore, all these features allow RA & RB series face mount crossed cylindrical roller bearings to suit for industrial applications that request a high accuracy of inner ring rotation and compact mounting space.
