Features of Automotive Oil Seal

Update:2018-04-27

Automotive oil seals can be mainly divided into outsourced plastic oil seals, exposed skeleton oil seals, semi-wrapping (half exposed skeleton) oil seals, cartridge oil seals, modular oil seals, pressure seal oil seals, adhesive oil seals, felt dust seals with lip seals, and patch oil seals etc.

The performance characteristics of automotive oil seal 

1. Installation is easy to deform: Improve the overall rigidity of the seal.

2. Spring tension attenuation: Increase spring tension and increase the compression force on the shaft.

3. Ingress of dust lead to seal failure: Increase the dust lip, use vulcanized rubber or felt structure.

4. Wear due to overheating: Using a well-cooled structure, pay attention to the amount of interference of the accessory lip and heat dissipation of the case.

5. Insufficient eccentricity resistance of the oil seal: The actual amount of interference is too large, the size of the structure is changed, and the waveform waist structure is used to improve the ability of the oil seal to withstand the overload deformation.

6. Insufficient pressure resistance leads to leakage: A pressure resistant structure is used.

7. Oil seal deformation result in Leakage: The sliding width at the deformed portion changes, improving the assembly jig.
