RA Crossed Roller Bearings

Inner Diameter: 50-200mm Outer Diameter: 66-226mm Width: 8-13mm Weight: 0.08-0.71kg

RA series cross roller bearing characteristics:

1. High precision: P4 precision, P2 precision.

2. High rigidity: This series bearing have preload.

3. High load: This series bearing can bear double-direction axial load, radial load and tilting moment.

4. Small size: This series bearing can save space for machine tools.

RA series cross roller bearing is a kind of small size and light weight cross roller bearing which the wall thickness is thinner. it is small and can with stand heavy load. So bearing housing and presser flange can be light wight. It can be suited for the hand location of the robots used in the rotary location.
