Functions of the various oil seal components:
1)Seal Lip Edge (shaft contact)
The seal lip has the cross-sectional profile of a wedge, and it presses down on to the shaft surface to seal in fluid.
2)Main Seal Lip
The seal lip is made of a flexible elastomer and is designed to maintain stable shaft contact and sealing even with machine vibration and fluid pressure fluctuation. A garter spring adds to the radial load and helps keep the sealing edge in proper contact with the shaft.
3)Dust Lip
A dust lip is an auxiliary spring-less lip, and acts to prevent dirt ingestion.
4)Seal Outer Diameter
The seal OD creates a press-fit to the housing bore, thus retaining the seal and preventing fluid escape. An internal metal case provides a solid backbone for rigidity.
Rubber Types and Characteristics Used in Beck’s Oil seals
NBR Resistance to oil, abrasion. -25~100 °C
This material is most often used in oil seals due to its excellent resistance to mineral oil and abrasion; however, oil seals made of this rubber cannot be used to polar solvents, such as ketone or ester.
FKM Resistance to oil, weather, abrasion, -40~250 °C
This rubber has heat resistance surpassing that of silicone. It also has excellent resistance to oils and chemicals. This material is the best rubber for oil seals due to its well-balanced characteristics.
