XRA-XRAC-XRBS

XRA (integral inner ring, separate outer ring, ultra-thin) this model is the XRB outer ring thickness
reduced to the limit of the compact, structure and XRB outer ring structure, suitable for heavy light, compact design, such as robot and manipulator rotating parts. The three types have the same shape and size. The difference lies in that the outer ring of XRA is transverse section, the outer ring of XRA-C is longitudinalsection, and the outer ring of XRBS series is integral structure.
