Radial/Lip Seals
Radial lip seals are the most widely used type of rotary seal, trusted across industries for their reliability, versatility, and cost-effectiveness. These seals are specifically designed to retain lubricants and exclude contaminants in applications where a rotating shaft passes through a stationary housing.
How They Work
The radial lip seal features a flexible sealing lip that maintains contact with the rotating shaft, creating a barrier that effectively keeps fluids in and dirt, dust, and other external elements out. The lip is typically energized by a spring to maintain consistent contact and pressure, even as components wear or temperatures fluctuate.
Key Applications
- Pumps and Compressors
- Motors and Gearboxes
- Automotive Drivetrains
- Industrial Machinery
- Agricultural and Construction Equipment
Design Versatility
Radial lip seals can be customized based on:
- Speed Requirements: Engineered to perform at low to high RPMs without compromising sealing integrity.
- Temperature Range: Available in materials that withstand both extreme heat and cold, making them suitable for demanding environments.
- Media Compatibility: Designed to handle oils, greases, water, chemicals, or slurry depending on application needs.
Available Options
- Single or Dual-Lip Configurations
- With or Without Dust/Exclusion Lips
- Various Elastomer and PTFE Sealing Materials
- Metal-Cased or Fully Rubber-Encased Options
Whether you're looking for a standard solution or a custom-engineered seal, radial lip seals offer proven performance for dynamic sealing in rotating applications.
