The sealing lip is crafted from nitrile rubber (NBR), specifically designed to withstand high temperatures and provide a strong barrier against oil and grease, ensuring long-lasting performance in demanding environments.

The precise dimensions, including a 25mm shaft diameter and 37mm housing bore diameter, ensure a snug fit, preventing leaks and maintaining the seal’s integrity during operation, which is Crucial in reducing maintenance needs.

It is important to maintain operating temperatures within -40°C to +100°C for optimal performance. Exceeding these limits can compromise the seal’s integrity and lead to premature failure.

The seal’s design, featuring a flexible sealing lip and a garter spring, allows for slight misalignments to be effectively managed, thus maintaining proper sealing pressure even when components do not align perfectly.
