Heavy Duty Shaft-Mounted Rotary Shaft Seals


Side 1	Side 2	Profile

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.

Spring-Loaded Rotary Shaft Seals with Wiper Lip


Side 1	Side 2	Profile

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.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Acrylic-Coated Case—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.

High-Speed Rotary Shaft Seals


Side 1	Side 2	Profile

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.

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


Side 1	Side 2	Profile

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.

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

Seal with Retainer

and Straight 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. Seal Width represents the working height, which is the compressed length when installed. The seat is comprised of the seat and the gasket.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Buna-N Diaphragm—Buna-N diaphragms resist grease and a wide range of oils.

EPDM Diaphragm—EPDM diaphragms are more resistant to water and steam than Buna-N and Viton® fluoroelastomer, but aren’t as resistant to oils and chemicals.

Viton® Fluoroelastomer Diaphragm—Viton® fluoroelastomer diaphragms resist a wider range of chemicals than Buna-N.

Buna-N Gasket—Buna-N gaskets resist grease and a wide range of oils.

Viton® Fluoroelastomer Gasket—Viton® fluoroelastomer gaskets resist a wider range of chemicals than Buna-N.

Carbon Washer—Carbon washers are for use with clean liquids.

Silicon Carbide Washer—Silicon carbide washers have a hard surface that resists scratching, so they can be used with liquids that contain abrasives.

Narrow-Profile Mechanical Pump Shaft Seals with Extended Spring

With a smaller seal OD than standards seals, these seals have an extended spring that accommodates variations in seal cavity length. They're used in waste water, boiler feed, and compressor pumps. Seals 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. Seal Width represents the working height, which is the compressed length when installed. The seat is comprised of the seat and the gasket.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
