Rotary Shaft 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.

High-Speed Rotary Shaft Seals

A slippery PTFE surface allows these seals to function at speeds at least 25% faster than other rotary shaft seals.

Split Rotary Shaft Seals

Swap out old seals without disassembling components—these seals come split for easy installation. They're also known as clipper seals.

Mechanical Pump Shaft Seals

Mechanical Pump Shaft Seals with Extended Spring

An extended spring on these seals accommodates variations in seal cavity length and pump misalignment.

Heavy Duty Mechanical Pump Shaft Seals

Multiple internal springs ensure these seals keep the sealing surfaces in contact in demanding applications, such as agricultural, chemical, and mining pumps.

High-Speed Mechanical Pump Shaft Seals

Built for high-speed circulation and dispensing pumps, these seals have a short spring that facilitates speeds up to 10,000 rpm.

Narrow-Profile Mechanical Pump
Shaft Seals with Extended Spring

These seals fit in housing bores that meet DIN 24960.

Mechanical Pump Shaft Seals

These seals are commonly used in well, sump, and displacement pumps.

Mechanical Shaft Seals

Commonly used in mixing and grinding equipment, conveyors, and construction machinery, these two-part seals withstand exposure to abrasive material.
