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.

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.
