Frequently Asked Questions (FAQs)

1. What is lip in oil seal?

When a lip seal is used on a steel shaft to seal mineral oil, as long as proper lubrication and proper pressure conditions are maintained wear is minimum and takes place only at start-stop conditions with almost infinite life of seal.

2. How should lip seals be installed?

The sealing lip should face the lubricant that requires sealing. The second lip on a double lip oil seal is intended as a dust lip. The seal must be installed at a 90°, or perpendicularly, to both the shaft and housing bore.

3. What is a shaft lip seal?

A sealing lip made of an elastomeric or thermoplastic material that seals dynamically and statically against the shaft. The lip has a sealing edge that is formed by moulding, cutting or grinding. It is normally pressed against the counterface surface of the shaft, with a defined radial load, by a garter spring.
