Seal damage or wear:
Cause: Damage or wear of bearing seals is one of the most common causes of oil leakage.
Seals may lose their original sealing properties after prolonged use due to aging, wear or mechanical damage.
Solution: Check the seal of the bearing regularly, and replace it with a new seal immediately once signs of damage or wear are found.
Improper installation:
Cause: Improper alignment or excessive force during bearing installation may cause deformation or damage to seals, resulting in oil leakage.
Solution: Ensure that bearings are installed in strict accordance with manufacturer's instructions, using the appropriate tools, and ensuring that bearings are properly aligned.
Bearing overheating: Reason: The bearing runs at too high a operating temperature, which may cause the grease to become thinner, making it easier to leak out of the bearing.
Solution: Monitor the operating temperature of the bearing to ensure that the bearing does not overheat. If necessary, take cooling measures or adjust the working conditions of the bearing.
Excessive oil addition: Reason: Too much oil is filled inside the bearing, which may cause the oil pressure to increase, forcing the oil to leak from the seal.
Solution: Add the right amount of grease according to the bearing manufacturer's recommendation to avoid overfilling.
Seal design is unreasonable: Reason: the seal design of the bearing may not be tight enough, or the material of the seal does not match the working environment.
Solution: Consider replacing a more suitable seal, or upgrading the sealing system of the bearing to improve the sealing performance.
Bearing wear or damage: Reason: the bearing may be worn or damaged after a long time of use, especially the damage of the raceway or roller surface, which will lead to reduced sealing performance.
Solution: Check the wear of bearings regularly and replace new bearings if necessary.
Maintenance and maintenance advice Regular inspection: Regularly check whether the seal of the bearing is intact, whether the grease is sufficient, and whether the bearing has abnormal noise or vibration.
Cleaning and maintenance: Keep the bearing around clean, to avoid impurities into the bearing inside.
Correct lubrication: Use the appropriate grease according to the manufacturer's recommendations and refill or replace the grease regularly. Through the above measures, the problem of oil leakage of tapered roller bearings can be effectively reduced, the service life of bearings can be extended, and the stable operation of mechanical equipment can be ensured.
