RA15008 cross roller bearing specifications:

* RA15008UU is two sides sealed type.

More RA cross roller bearing models

RA15008|RA15008UU crossed roller bearing features:

1. Integrated inner ring with separable outer ring.

2. Sustain radial, axial and moment loads at the same time.

3. High rigidity & running accuracy.

4. Ultra-thin section, space saving and reduce the overall weight of the device.

Advantage of RA15008/RA15008UU bearings

Both inner ring and outer ring of RA15008 crossed roller bearing are solid one-piece type, with integrated raceway, outer ring has a loading plug for assembling rollers. The width of RA series slewing bearing is the thinnest among RA/RB/RU/RE series cross roller ring. So this series is specially suited for limited space, and applications which require rotation accuracy of both inner and outer ring.

RA15008 cross roller bearing installation instructions

Cautions: For crossed roller bearings with split outer ring, when the rigidity of the mounting parts is not sufficient, stress concentration will occur at the contact area between the rollers and raceways, and the bearing performance will be deteriorated significantly.

Therefore, it is necessary to carefully examine the rigidity of housing and the strength of fixing bolts when a large moment will be applied.

1. Before installation, please clean bearing bracket, shaft, or other components, make sure there is no burrs or rough edge.
2. Fix the inner and outer rings in the axial direction by using fixing plates, etc.
3. Slightly loosen the fixing bolts of bearings outer ring during mounting.
