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.
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.
