For sealing dynamic, rotary motion
Example of a rotary seal installation
Rotary seal profile view example
The primary function of a rotary seal is to retain the bearing lubricant and, secondarily, to enhance the performance and life of the bearing by minimizing dirt, oil and water ingress that leads to damage and premature failure of the bearing and other components.
Our Rotary Seals are classified as follows:
- Oil, Grease and Bearing Seals
up to 7psi (0.5bar)* pressure spikes, 5,000fpm (25m/s)*
- High and Medium Pressure Rotary Seals
up to 20,000psi (1,380bar)*, 5,000fpm (25m/s)*
- Rotaflon™ High-Performance Rotary Seals
for low friction and low energy consumption, extended seal life, dry run, high speeds up to 10,000fpm (50m/s)*
- Split Rotary Shaft Seals
for easy replacement installation
- Swivel Seals
for slow rotating and high pressure sealing applications
- Labyrinth Type Seals
non contact exclusion seals

Availability Most standard or non-standard and application-specific designed rotary shaft seals, in inch or metric sizes, are available with a 1-4 day turnaround.
For your unique or special rotary seal application, contact our engineers to help you in specifying a seal that’s best suited for your situation.
* Maximum values depend on seal material, seal configuration, media, temperatures, pressures, surface speed and working environment. For maximum seal life expectancy, do not operate your seal beyond 75% of its operating limits. Please consult our engineers or call 1-800-283-7140 for advice.
