    RAU6005 crossed roller bearing features:

    1. Compact structure, suited for applications which require high rotation accuracy of both inner and outer ring.

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

    3. High rigidity & running accuracy.

    4. Ultra-thin section and lightweight.

    5. Custom design available.



    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. What’s the lead time of this model RAU6005?
    Since RAU6005 belongs to small-diameter thin section crossed roller bearings, the production processing is more difficult and complicated than common type cross roller rings. Bearing rings are easy to get deformed during heat treatment and processing, and the rejection rate is higher too. The average lead time of RAU cross roller rings is 45~60 days.

  • RAU6005 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.

    RAU1505 bearing installation

    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.
