This specific designation usually corresponds to a standardized metric dimension, defining a seal with an internal diameter of 78 mm, an external diameter of 88 mm, and a thickness of 7 mm. The industrial manufacturing space relies on them for pumps, motors, and hydraulic cylinders, ensuring that expensive lubricants are retained and critical machinery operates smoothly.

They are typically composed of a robust metal outer shell, which provides structural integrity and allows for precise installation into a housing bore. 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.
This dynamic lip maintains a thin film of the lubricant being sealed, creating a friction surface that is critical for the seal's longevity and effectiveness in preventing leakage. 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.

In more demanding scenarios involving high temperatures, aggressive chemicals, or harsh environmental conditions, FKM seals are utilized, offering superior thermal stability and chemical resistance that significantly extends service life. Troubleshooting Leakage and Failure When leakage occurs, it is often a symptom of an underlying issue rather than a simple seal defect.
