Rotary Shaft Seals

The ubiquitous rotary shaft seal is often taken for granted, however careful consideration of operating paramaters at the design stage can often lead to longer life and optimised performance.

Several features need to be factored into seal design:-

• Is an external static seal needed?
• Is a dust lip to prevent ingress of foreign matter required?
• What media are to be sealed?
• Are the seal and tension spring materials compatible with this media
• Circumferential speed
• Upper and lower temperature limits
• Will the seal be pressurised?
• Are there vibrations, or heavy loads?
• What shaft and housing sizes are readily available?

All of these factors affect seal choice, to ensure leak tightness, reliability, compatibility, low friction and easy fitting.
