How to check

To determine whether a SB oil seal needs to be replaced, you can start from the following aspects:

1. Visual inspection
2. Check the wear: check the lip part of the oil seal, which is the key part of the seal, if the lip is obviously worn will affect the sealing effect, it needs to be considered to be replaced
3. Check the signs of aging: check whether the surface of the oil seal is hardened, embrittlement, or cracks, cracks and other problems, if there is, it indicates that the oil seal is aging, the sealing performance is reduced, and it should be replaced in time.
4. Watch for oil leaks: Regularly inspect the ground around the oil seal and at the bottom of the equipment
