About Rotary Shaft Seals

Also called radial shaft seals, rotary shaft seals help retain lubricants between rotating shafts and components that are mounted to the shaft. Properly fitted shaft seals also help prevent dirt, moisture, and other contaminants from entering lubricated parts.

Rotary shaft seals consist of a rigid housing and one or more flexible lips made from elastomeric materials. The housing sits flush against the shaft-mounted component, and the lip flexes to form a seal between the component and the shaft. For best results, shaft seals should be used on smooth, undamaged shaft surfaces or worn shaft surfaces that have been repaired with a shaft wear sleeve.

The rubber case on these oil-resistant seals provides excellent sealing even in rough or split housings. These seals also have a spring-loaded lip and a beaded outside diameter for improved sealing ability and better oil retention.
