How to deal with oil leakage of floating oil seal

1. Master and recognize the basic knowledge of fake and inferior products, and purchase high-quality and standard oil seals.

2. During installation, if the surface roughness of the shaft diameter is low or there are defects such as rust, rust, burrs, etc., use a fine emery cloth or whetstone to smooth it; apply clean engine oil or lubricating grease to the lip of the oil seal or the corresponding position of the shaft diameter.

3. Apply sealant to the outer ring of the oil seal, wrap the keyway on the shaft with hard paper to avoid scratching the lip of the oil seal, use a special tool to rotate and press the oil seal inward, and don't smash it hard. The oil seal deforms or squeezes off the spring to make it ineffective; if there are lip cuffs, 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 spring force of the oil seal spring is sufficient, do not tighten the inner spring without authorization.

4. Oil seals applied to machinery generally have to be inspected, maintained and maintained when the general working conditions are poor, the ambient temperature difference is large, the dust is excessive, and the vibration of the machine tool frequently changes the stress condition of the machine parts.

5. For abnormally heated parts or assemblies, the fault should be eliminated in time; avoid mechanical overspeed and overload operation to prevent the temperature of the oil seal lip from rising, rubber aging, and early wear of the lip.

6. Always check the oil level of the engine oil. If there are too many impurities in the engine oil, and if there are alloy powders and metal iron filings, replace the engine oil completely. The brand and quality of the oil to be replaced must meet the requirements of the season.
