    1. How to maintain crossed roller bearings?
    Unless otherwise stated, all BRS made RAU series crossed 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 operation, bearings should be added with proper grease based on working conditions.


    2. I’m designing a prototype, can you produce according to my design?
    Yes, BRS can produce a custom design based on users’ requirements, but there will be a MOQ.


    3. What is the warranty of this RAU2005 crossed roller bearing?
    BRS provide one year warranty for RAU crossed roller bearings that working under common working conditions. We have excellent after-sale service to help users during the installation and application of bearings.

  • RAU2005 bearing installation instructions

    Cautions: For crossed roller bearings, 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.
