Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.

A rotary shaft seal, also known as a lip seal or radial seal, is a device that creates a barrier between two environments the area where the rotating shaft operates and the external atmosphere. In high-pressure applications, these seals are engineered to withstand significant operational pressures, often exceeding several thousand psi. They are utilized in applications such as hydraulic pumps, turbines, and engines, where preventing fluid loss is critical.

1. Edge Finishing One of the primary uses of a serger machine is to finish the raw edges of fabric, especially knits and woven fabrics. The overlock stitch formed by the machine encases the fabric edges in yarn, thereby preventing fraying.
