Auto Oil Seal

In auto oil seal applications, lip seals secure the application from high pressures as they provide a tighter sealing action, automotive oil lip seals are available in a variety of configurations to support a wide range of industries and their different requirements . There are several types of oil lip seals. They are available in a variety of materials and sizes. They can be made with or without springs. The most commonly used oil lip seals include: External oil seal, Single oil seal, Dual oil seal, Flange Case oil seal, PTTE oil seal and more.If you have questions about car sealing, please contact us.


Auto Oil Seal Structure

The oil seal is generally composed of three basic components: sealing element, metal shell and clamping spring.Types of oil seals include single and double lips, rubber or polymer, metal housing, spring loaded, and internal, external and axial guides.

The purpose of the sealing element is to stop the leakage of fluid between the shaft and the housing. The metal housing will give rigidity and strength to the sealing element when it is held in a bore or recess. The spring will help make the sealing element more effective. All materials must be selected according to the environment in which the oil seal will be placed.


Auto oil Seal Features

1. Isolation of dust and prevention of leakage of hydraulic oil and gas.
2. Reciprocating operation to exclude contamination.
3. Double steel shell design, enhanced structure, enhanced ability to exclude dust, dirt and sludge.
4.Screw design to reduce friction, seal, exclude dust and protect axle and bearing from dust, grit, mud and other contamination.
