Bore-Sealing Spring-Loaded
Rotary Shaft Seals with Wiper Lip
Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing. Also known as oil seals, these retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. They have a secondary lip that blocks contaminants and a spring that secures the sealing-lip to prevent leaks. Press-fit seals into the bore around the shaft. Seals with a maximum pressure of 145 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.

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.

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.

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.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

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 ID, OD, and 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.
