    1. What is the MOQ of SHF-45 reducer gearhead output bearings?
    There is no MOQ for bearing models in stock, and low MOQ for custom design. Please contact us for details.


    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.


    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.

    SHF gear units cross roller bearing installation


    1. Before installation, please clean bearing bracket, shaft, or other components,

    make sure there is no burrs or rough edge.


    2. Install the screws to connect crossed roller bearings with circular spline,

    then install the screws to connect bearings with flex spline.


    3. Install the wave generator and related components.
