Understanding High Pressure Rotary Shaft Seals

4. Lip Seals Lip seals are suitable for both dynamic and static sealing applications. They feature a lip that runs along the surface of the cylinder, creating a barrier against fluid leakage.

A double lip oil seal typically consists of a rubber or elastomeric body with two sealing lips and a metallic casing that provides structural support. The primary seal, which is located on the inside, forms a tight contact with the rotating shaft, while the secondary lip serves as an additional barrier, providing extra protection against oil leakage and dust ingress. The design of double lip seals allows for greater flexibility and adaptability to various operational conditions, making them suitable for a wide range of industries.
