1, Provide proper tolerance for the shaft, do not over-tighten.

2, When installing the sealing hole and the ring, grease should be applied to reduce frictional resistance.

3, The slewing bearing will remove excess grease through the sealing hole and reduce the lubricating oil level below the bearing housing.

4, Re-select the appropriate type of lubricating oil.

5, The oil level on the outside of the shaft diameter should be just lower than the cage, add suitable grease.

6, Stop the machine and check the clamping screw to ensure that the inner ring is firmly attached to the shaft and that the free end bearing is installed correctly.
