More RB crossed roller bearing models.
1. Integrated inner ring with separable outer ring, clearance can be adjusted.
2. Sustain radial, axial and moment loads at the same time
3. High running accuracy supplied with normal clearance, little clearance or even under a pre-load
4. Stable rotation, spacer retainer prevents rollers from from skewing, thus eliminates friction between rollers, and avoid increasing of the rotation torque
1. Which precision grade shall I select?
There are mainly three precision grade for RB series crossed roller bearing, P5, P4 and P2. The table below shows RB14025 runout tolerance of each grade, users can select based on their actual application and requirements. If you are not sure how to choose, don’t hesitate to contact us, our engineers will offer you suggestions.
Accuracy | P5 | P4 | P2 |
Radial run-out of inner ring | 8μm | 6μm | 2.5μm |
Axial run-out of inner ring | 8μm | 6μm | 2.5μm |
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.
