Bonded to this metal casing is a flexible sealing lip, usually made from nitrile rubber (NBR) or fluoroelastomer (FKM), which is tensioned against the rotating shaft or stationary housing. The process requires meticulous attention to detail to avoid damaging the delicate sealing lip.

The bore and shaft must be impeccably clean and free of any burrs or sharp edges that could cut the lip. They are typically composed of a robust metal outer shell, which provides structural integrity and allows for precise installation into a housing bore.
Furthermore, agricultural equipment and construction machinery utilize these robust seals to safeguard components from the constant assault of dust, dirt, and moisture inherent in those working environments. The elastomer lip must possess specific chemical and physical properties to withstand the operational environment.

Their fundamental purpose is to create a reliable barrier, ensuring that critical fluids such as oils and greases remain contained while preventing the intrusion of dirt, dust, and other abrasive particles that can lead to premature equipment failure. For applications involving standard mineral oils and moderate temperatures, NBR is the industry standard due to its excellent resistance to petroleum-based fluids.
