RA5008UUCC0 crossed roller bearing product advantage:
High Rigidity Type Crossed Roller Bearings
Both inner and outer rings have a solid one-piece
construction. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized. As separators are incorporated between the cylindrical rollers for smooth rotation, these bearings are suitable for applications where rotational speed is comparatively high.

RA 5008UUCC0 bearing Installation Procedure
(1) When attaching the presser flange, attach it to the integrated rotation ring (i.e., inner ring of models RB and RA, or outer ring of model RE) first.
(2) Place the presser flange onto the Cross-Roller Ring. Rock the flange several times to match the bolt holes.
(3) Insert the presser bolts into the holes. Manually turn the bolts and make sure they do not display skewing caused by misalignment of the holes.
(4) Tighten the presser bolts in three to four steps from light to full tightening by repeatedly securing the bolts in diagonal order.
When tightening the separable inner or outer ring, slightly turning the integral outer or inner ring will correct the dislocation between the ring and the body.
