(THK RA series crossed roller bearings, RA-C series crossed roller bearings, IKO CRBS series crossed roller bearings)
RA Cross roller bearings are designed to offer an more compact type of RB series crossed roller bearings. The bearing features all attributes of RB series crossed roller bearings while conserving space with thin inner and outer ring. Because of its vertical arrangement of rollers in a 90°V, the bearing is capable to carry loads in all directions at the same time: radial,axial and moment loads. Thus, the bearing housing and presser flange can be lightweight. It is optional for areas where the swiveling units need to be lightweight. Combined with its high rigidity, it can be applied to the joints and rotating parts of industrial robots, rotary tables of machining centers, medical equipment, measuring instruments, rotating parts of manipulators, precision rotary tables, etc.
