RB cross roller bearing

RB is a standard type with thinnest possible inner and outer rings. It is optimal for locations where the rotational accuracy of the inner ring is required.

Note 1: nominal model with seal ring is RB***UU.

Note 2: in the high-precision, please use the inner ring rotation way.
