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.

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.

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.
