    1. What is the MOQ for this model RA13008?
    There is no MOQ for bearing models in stock, and low MOQ for a custom design. Please contact us for details.


    2. Can I get a drawing of this model?
    Yes, we provide drawing for standard bearing models, and can also produce custom design according to your drawing.


    3. How to lubricate RA series crossed roller bearings?
    Unless otherwise stated, all BRS made RA cross roller bearings are filled with the proper amount of complex lithium grease before delivery. So users can directly put bearings into the application after receiving goods. Then after 1~6 months of operation, bearings should be added with proper grease through grease holes on the outer ring based on working conditions.

  • RA13008 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.
