Large thin chrome steel 80*165*22 mm cross roller bearing RU124X RU148 RU178 RU228 RU297 RU445 for vertical grinders

TCross roller bearing feature :
1. Excellent rotation accuracy
2. Operational installation simplification
3. Withstand large axial and radial loads
4. Significantly save installation space
5. High speed capability
6. Reduce shaft length and machining cost, thermal expansion leads to limited variation in geometry
7. Nylon separator, low moment of inertia, low starting torque, easy to control angular division
8. Optimize the pre-tightening force, the rigidity is high, and the guiding roller has high running precision.
9. Carburized steel provides excellent impact resistance and surface abrasion resistance
10. Simple but fully lubricated

Product Description:

        The crossed roller bearing is a special type of bearing with inner ring splitting and outer ring rotation. Since the divided inner ring or outer ring is fixed to the cross roller collar after being loaded into the roller and the spacer, to prevent separation from each other, the operation is simple when the cross roller collar is installed. Since the rollers are arranged in a cross, only one set of crossed roller collars can withstand loads in all directions. At the same time, because the inner or outer ring of the crossed roller bearing is a two-part structure, the bearing clearance can be adjusted.
