RA Crossed Roller Bearings

Features : RA series crossed roller bearings, Split outer ring, intergrated inner ring, Ultra thin
Inner Diameter: 50-200mm Outer Diameter: 66-226mm
Width: 8-13mm Weight: 0.08-0.71kg Precision: P5, P4, P2
High rigidity: This series bearing have preload
High load: Can bear double-direction axial load, radial load and tilting moment
Small size: This series bearing can save space for machine tools
HRA 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
