The countermeasures for oil leakage due to inadequate sealing of oil seals

1. Master and identify the basic knowledge of counterfeit and inferior products, and choose high-quality and standard oil seals.

2. When installing, if the outer surface of the shaft diameter is low in roughness or has defects such as rust spots, corrosion, burrs, etc., it should be smoothed with a fine emery cloth or oil stone; apply clean engine oil or grease to the oil seal lip or the corresponding position of the shaft diameter. Coat the outer ring of the oil seal with sealant, and wrap the keyway on the shaft with hard paper to avoid scratching the oil seal lip. Use a special tool to rotate the oil seal inward, and do not hit hard to prevent the oil seal from deforming. Or squeeze the spring to fail; if the lip flanging, the spring falls off and the oil seal is skewed, it must be removed and reinstalled. It should be noted that when the shaft diameter is not worn and the oil seal spring has sufficient elasticity, do not tighten the inner spring without authorization.

3. The oil seals used in machinery generally have bad working conditions, large environmental temperature differences, a lot of dust, frequent machine vibrations, and frequent changes in the force of the machine parts should be inspected, maintained and maintained frequently.

4. If the shaft diameter and bearing wear is severe; the oil seal rubber is aging or the spring fails, etc., repair and replace the corresponding parts in time.

5. Troubleshoot the abnormal heating components or assemblies in time; avoid mechanical overspeed and overload operation to prevent the oil seal lip temperature from rising, rubber aging, early lip wear, etc.

6. Always check the oil level of the engine oil. If there are too many impurities in the engine oil, if there are alloy powders and metal iron filings, the engine oil must be completely replaced. The brand and quality of the oil to be changed must meet the requirements of the season. It is recommended to add Metre Super Sealant & Lubricant to the engine oil. It is an excellent gearbox additive that can form a thin film of inert material on the components, which can slow down the leakage of the oil seal and extend the use of the oil seal gear Longevity can also reduce the noise of the gearbox. The use of this Super Seal Lubricant will not pollute or deteriorate the oil.
