    1. What’s the rotation precision of SHF40-XRB crossed roller bearings?
    The standard running accuracy of SHF-40 output bearings is P5, which can meet the requirements of most applications. BRS can also supply higher precision level, please contact us with your detailed requirements.


    2. What is the MOQ of SHF-40 gearbox output bearings?
    There is no MOQ for bearing models in stock, and low MOQ for custom design. Please contact us for details.


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