RB Series

RB series are basic type of cross roller bearing with the minimal dimensions of inner ring and outer ring. The str align="center"ucture of separable outer ring and integrally designed inner ring makes it suitable to where high rotational accuracy of the inner ring is required. RB series include two types: RB (open type) and RB···UU (two sides sealed type).
