What Is a Rotary Seal?

A rotary seal is designed to prevent the leakage of fluids, solids, or contaminants. It operates using two primary principles: lip seals and mechanical seals. Lip seals, typically made of rubber, employ a circular lip that compresses the gap using hydraulic pressure or springs to block leakage. Mechanical seals, on the other hand, utilize the precise fit of their components to achieve the same goal.

Rotary seals are integral to industrial machinery, automobiles, and household appliances. They are categorized into mechanical and non-mechanical types. Mechanical seals rely on the configuration of their components to prevent leakage, whereas non-mechanical seals use specific materials for this purpose. Their crucial role is to create a leak-proof barrier between rotating shafts and stationary parts, making them versatile for various applications. When choosing a rotary seal, it is vital to consider the seal's type and size, factoring in the intended environment and application.
