THK RA series crossed roller bearing characteristics:
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 install 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
• Measuring instruments
All THK RA series crossed roller bearing models:DK bearing THK type RA8008 Crossed Roller Bearing has high rigidity, loading capacity and rotation accuracy. It has integrated inner ring and separable outer ring, share the same structure with RB crossed roller bearing except it’s ultra-thin. Suited for where light weight, compact design are required, such as the swiveling units of industrial robot or manipulators.
