    1. How to lubricate XSU080188 cross roller bearings?
    Unless otherwise stated, all BRS made XSU series 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.


    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.
