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.
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.

Bore-Sealing Spring-Loaded Rotary Shaft Seals with Wiper Lip
 |  |  |  |
Side 1 | Side 2 | Profile |
Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing. Also known as oil seals, these retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. They have a secondary lip that blocks contaminants and a spring that secures the sealing-lip to prevent leaks. Press-fit seals into the bore around the shaft. Seals with a maximum pressure of 145 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.

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.

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.

Split Rotary Shaft Seals
 |  |  |  |
Side 1 | Side 2 | Profile |
Replace old seals without disassembling components—these seals come split for easy installation. Also known as clipper seals, they retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip to prevent leaks; fasten the hook and eye closure to secure. Press-fit seals into the housing bore; they fit tight for installation without a cover plate.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
