RB Type (with two outer semi-rings and an inner ring)
The RB series are the basic type of the crossed cylindrical roller bearings. The dimensions of their inner and outer rings are minimized. Each outer ring is two semi-rings that are fixed with bolts or special rivets. Each inner ring has a one-piece design. The series are suitable for parts which require high rotation accuracy of inner rings, such as the rotating parts of the indexing workbenches of machine tools.
