Radial shaft seals

Radial shaft seals: static and dynamic performance

Radial shaft seals sit between rotating and stationary components, or two components in relative motion.

They have two main parts. One is a cylindrical outer covering with an interference fit that seals statically against the housing bore. The second, a sealing lip, seals dynamically and statically against the shaft. Its sealing edge presses against the counterface surface of the shaft with a defined radial load.

Differentiation Criteria

- Sealing lip materials have high chemical/thermal resistance
- Superior pump rate
- Special coating compensates for housing bore surface imperfections
- Robust design
- Compliant with national and international standards
