1. Check the accuracy of the axis
Before installing the bearing, check whether the dimensional tolerance of the shaft is qualified, whether the shaft has bending, collision, burrs and other problems, and add lubricating oil appropriately on the shaft.
2. Check the rigidity and flatness of the installation surface
The rigidity of the frame for installing bearings with seats should be sufficient, and the flatness of the installation site should not exceed 0.15mm.
3. Install seat bearings
Avoid using metal objects such as hammers to strike the bearings during installation. Especially for bearings with retaining ring seals, knocking on the bearing may cause the retaining ring to move inward and come into contact with the inner sealing ring, resulting in friction during operation and causing the bearing to rotate poorly or experience a rapid temperature rise, which can burn out the bearing. When the bearing inner hole is tightly matched with the shaft, it is recommended to use a pressure device to press the inner ring end face for installation.
4. Pre tighten the bearing seat
Excessive torque of the locking bolt may cause deformation of the bearing seat, and appropriate tightening torque is required to lock the bolt Zhongda Bearing recommends using the locking bolt and gasket together when installing the bearing seat, as using the locking bolt alone to lock the bearing seat may cause damage to the bearing seat.
5. Tighten the bearing top thread
The torque for locking the top thread should be the recommended torque.
6. Tighten the bearing seat again
Excessive torque of the locking bolt may cause deformation of the bearing seat, and appropriate tightening torque is required to lock the bolt
