The Parker SEAL-H1L5-9511 Clipper Oil Seal is a high-performance rotary shaft seal engineered to provide exceptional grease retention and dust exclusion in various industrial applications.
Key Features
- Low Friction Elastomer Lip: The seal features a soft, thin, and flexible elastomer lip that minimizes friction, reducing wear and extending the service life of both the seal and the shaft.
- Composite Rubber/Aramid Fiber Outer Case: The Clipper® non-metallic outer case, made from a composite of rubber and aramid fiber, ensures a damage-free installation and conforms to minor bore surface irregularities, providing a leak-free, press-fit in the housing.
- Spring-Loaded Design: Equipped with a stainless steel garter spring, the seal maintains a constant, uniform load on the lip against the shaft, accommodating higher shaft speeds and compensating for normal compression set and wear of the lip material.
