Rotary Seals
Oil Seals, Grease Seals, Bearing Seals
Rotary Shaft Seals, Radial Lip Seal and Rotary Seals for sealing dynamic, rotary motion


For oil and grease retention, no pressure or very low pressure up to 3psi (0.2bar)*
The primary function of oil seals, grease seals and bearing seals is to retain the bearing lubricant and, secondarily, to enhance the performance and life of the bearing by minimizing dirt, oil and water ingress that results in damage and premature failure of the bearing and other components. …More Info
For continuous pressures above 3psi (0.2bar), see High- and Medium-Pressure Rotary Seals.
Our Oil-, Grease- and Bearing Seals are categorized as follows:

Spring-loaded double-lip oil seal
Premium spring-loaded double-lip oil seal with integrated steel reinforcement element. Used for oil or grease retention.
The optimized seal lip design uses a garter spring to maintain a constant radial lip load, thus ensuring optimum sealability. The rubber covered OD press fits to create a positive seal with the housing bore. The rubber OD also provides optimal compensation for housings of different thermal expansion, reducing possibility of fretting corrosion in soft alloy or plastic housings, and accommodating higher surface roughness of the housing bore. The secondary lip serves both as an effective protection against light airside contaminants and as a lube retainer. Maximum service life can be achieved by…

Valve stem seal
A valve stem seal is a positive seal that is pressed into place at the end of the guide and wipes the oil off of the valve stem as it reciprocates. Tight control of the fit allows a small amount of oil to pass the seal

High-pressure single-lip oil seal
This seal style is designed to minimize friction and aid in the development of low-noise power steering systems. The solid captured insert leads to reduced friction, increased extrusion resistance, and reduces contamination. Temperature range and fluid resistance can be matched due to correct elastomer and polymer selection.

Large bore tolerance single-lip oil seal
This seal is used in applications where there is a large tolerance on the housing root diameter or the housing is split. The rubber fabric OD also prevents damage to the housing due to corrosion and makes installation and removal a simple process. A cover plate is required to ensure proper compression and stability. This seal style is also available with a finger spring to handle shaft misalignment or run-out.

*Maximum values depend on seal material, seal configuration, media, temperatures, pressures, surface speed, dynamic running surface finish and working environment. Data provided are guidelines for ideal operating conditions. Seals cannot be operated at their upper pressure and speed ratings at the same time. For maximum seal life expectancy, do not operate your seal beyond 75% of any of its operating limits. Please consult engineering or call 1-800-283-7140 for advice.
