Spring-Loaded Rotary Shaft Seals with Wiper Lip
Side 1
Profile
Side 2
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.
