40x55x8 oil seal

Wiper oil seals, commonly referred to as lip seals or simply oil seals, are mechanical seals used to keep lubricants in and contaminants out of machinery. They are typically made from durable materials such as rubber or elastomers, designed to withstand high pressures and temperatures. The primary function of these seals is to maintain a barrier that prevents the escape of oil, while also preventing dirt, dust, and other contaminants from infiltrating the system.

Definition and Design

In the aerospace industry, wiper seals help maintain the integrity of hydraulic systems in aircraft, where contaminants can have catastrophic consequences. Their ability to function effectively under extreme pressures and temperatures makes them indispensable in these high-stakes environments.

The typical construction of a skeleton oil seal includes an outer casing that fits snugly into the housing, a sealing lip that makes contact with the rotating shaft, and a metallic reinforcement that provides rigidity. This combination of materials ensures that the seal is capable of handling the dynamic conditions of machinery while maintaining an effective barrier against the ingress of dirt and the egress of lubricants.
