1. Integrated inner and outer ring, provide high stiffness.
2. Standard model XU050077 bearing is with a groove on the outer diameter of outer ring.
3. Support high radial loads, moderate axial loads and tilting moment loads.
4. High rigidity & running accuracy.
5. Easy installation, bearings can be screw mounted directly to the adjacent construction.
1. What is the hardness of this XU050077 cross roller bearing?
Usually crossed roller bearings are after integral quenching, its hardness can reach to HRC 58~62.
2. I’m designing a prototype, is there a MOQ and can you produce according to my design?
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 XU 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.
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 directly to the mounting surface by fixing bolts.
3. If large number of radial load and/or moment is applied, it is recommended to prepare flange part as Fig.4.
