Dynamic Seals

Bore-Sealing Spring-Loaded
Rotary Shaft Seals with Wiper Lip

Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing.

Spring-Loaded Rotary Shaft Seals with Wiper Lip

These seals have a metal case that creates a tight seal when mating with smooth surfaces.

Spring-Loaded Rotary Shaft Seals

Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft.

Spring-Loaded Rotary Shaft
Seals for Misaligned Shafts

Designed with an extended lip, these seals have the flexibility to accommodate shaft misalignment up to 0.125". They're also known as clipper seals.

Rotary Shaft Seals for Grease

Also known as grease seals, these are designed to retain thick lubricant at low pressure. They have a light grip on the shaft that creates less friction than spring-loaded seals.
