Spring-Loaded Rotary Shaft Seals with Wiper Lip
Used to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes, these seals have a secondary lip that blocks contaminants. Also known as oil seals, a spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft. Seals with a maximum pressure of 50 psi should be secured with a retaining ring.
Seals with an acrylic-coated case have a coating that compensates for surface imperfections in the housing bore for a tight seal on the OD.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Rotary Shaft Seals for Grease
Also known as grease seals, these are designed to retain thick lubricant at low pressure in motors, pumps, bearings, and gearboxes. They have a light grip on the shaft that creates less friction than spring-loaded seals. Press-fit seals into the bore around the shaft.
Seals with an acrylic-coated case have a coating that compensates for surface imperfections in the housing bore for a tight seal on the OD.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

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. Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. An O-ring secures the lips to prevent leaks, while sealing against the housing. Press-fit seals into the bore around the shaft.

Heavy Duty Shaft-Mounted Rotary Seals
These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F. Also known as V-rings and flingers, they protect shaft bearings by blocking dust and other contaminants while retaining lubricant. To install, stretch the seal over your shaft and press it firmly against the face plate.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Mechanical Pump Shaft Seals with Extended Spring
For use in waste water, boiler feed, and compressor pumps, these seals have an extra-long spring that accommodates variations in seal cavity length. They come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. The seat is comprised of the seat and the gasket. Products cannot be sold outside North America due to restrictions.
Buna-N diaphragms and gaskets resist grease and a wide range of oils.
Viton® fluoroelastomer diaphragms and gaskets resist a wider range of chemicals than Buna-N.
EPDM diaphragms are more resistant to water and steam than Buna-N and Viton® fluoroelastomer, but aren’t as resistant to oils and chemicals.
Carbon washers are for use with clean liquids.
Silicon carbide washers have a hard surface that resists scratching, so they can be used with liquids that contain abrasives.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
