THK ‌‌ crossed roller bearing RA series is a thin-walled bearing, It carries heavy loads. Because of the divided inner or outer ring, are attached to the roller and spacer after the roller and spacer are installed to prevent separation from each other, so when installing the cross roller ring easily, Since the rollers are arranged in a cross arrangement, only one set of crossed roller ring can withstand loads in all directions, and the rigidity is increased by 3 to 4 times compared with the conventional models. At the same time, since the inner ring or the outer ring of the crossed roller bearing has a two-divided structure, the bearing clearance can be adjusted, and even if a preload is applied, a high-precision rotational motion can be obtained.

THK RA series crossed roller bearing applications:

•Industrial robot arms, reducers

•Precision machines( turnable table)

•Rotation parts of Machine tools

•Medical equipments

• Measuring instruments
