More RA cross roller bearing models
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.
1. How to select crossed roller bearings?
Crossed roller bearings performance has an irreplaceable role in mechanical equipment, so selecting bearings require careful consideration. BRS suggest users choose cross roller ring following the procedures shown below. If the mounting space is very limited, and user has high requirements on the rotation accuracy of inner ring, then RA crossed roller bearing should be selected.
2. I’m designing a prototype, can you produce according to my design?
Yes, BRS can produce custom design based on users requirements, but there will be a MOQ.
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.
