High Precision RA 18013 Crossed Roller Bearings

High Rotation Accuracy of RA18013 Cross Roller Bearing/ CRBS 18013 Bearings

With the Cross-Roller Bearing, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90 degree V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads.

The outer ring of the Standard Type Crossed Roller Bearings is made of two split pieces, which are bolted together to prevent separation during transportation or mounting, enabling easy handling. These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel and those with inner and outer rings provided with mounting holes are also available on request.


● High Rotation Accuracy of RA18013 Cross Roller Bearing/ CRBS 18013 Bearings

● Significantly Increased Rigidity (Three to Four times Greater)

Unlike the thin angular ball bearings installed in double rows, the cross array of rollers allows a single Cross-Roller Ring unit to receive loads in all directions, increasing the rigidity to three to four times greater than the conventional type.
