Spring-Loaded Rotary Shaft Seals
Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. 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.

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.

Shaft-Mounted Rotary Seals
Also known as V-rings and flingers, these seals protect shaft bearings by blocking dust and other contaminants while retaining lubricant. They’re Buna-N for excellent resistance to oil and grease. To install, stretch the seal over your shaft and press it firmly against the face plate. The Seal OD and Seal Width listed are the dimensions of the seal after it is installed.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Heavy Duty Shaft-Mounted Rotary Seals
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.
