XRA series is the wall thickness of the inner and outer rings made very thin cylindrical cross roller bearings, small footprint and can withstand heavy loads, ideal for a robot or industrial robot hand portion of the rotary joints. The outer ring 2 is divided structure, through the integral rivets.
RA series crossed cylindrical roller bearing, this model is to type RB inside and outside the ring thickness decreases to the limit of the compact, as outer ring structure and RB series fission structure, the most suitable for the need of light weight, compact design, such as mechanical rotating parts.
