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:
-Standard Oil Seals, Grease and Bearing Seals

Spring-loaded single-lip oil seal
Premium spring-loaded single-lip rotary shaft seal made from low friction elastomers with integrated steel reinforcing 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, making it ideal for reducing the risk of fretting corrosion in soft alloy or plastic housings. A higher surface roughness of the housing bore may be accommodated by this seal style. For dirty, dusty or polluted environments, our AS…

Spring-loaded metal-cased single-lip oil seal
Premium spring-loaded single-lip rotary shaft seal with precision ground metal OD. Used for oil or grease retention.
This type is also the most economical design for general-purpose rotary sealing applications. An optimized seal lip with a garter spring maintains a constant radial lip force for optimum sealing. The metal case is exposed to the elements and to the fluid, however, the application of an optional sealant coating to the case, improves both static sealing and corrosion resistance between the housing and the seal OD. For dirty, dusty or polluted environments, our BS style with additional dust lip should be used.

This style offers higher shaft runout (up to 0.020” and misalignment up to 0.035”) than traditional oil seals. This seal design eliminates spring dumping. The solid rubber design allows the seal to snap into a closed groove; alternatively, a retainer ring can be used to hold the seal in place for open groove installation. Fitment in many challenging seal locations is possible with this design. This style is available in a wide range of elastomers and small quantities for repairs and seal replacement can be shipped in 1 to 3 days.

RLSRLS
Heavy-duty single-lip oil seal
Heavy-duty single-lip rotary shaft seal design for use in harsh and severe environments and shock loads.
Designed to handle harsh or arduous conditions where most seals have a short life. This style has higher shaft run-out and misalignment than traditional oil seals. Available in many metal and lip materials, this seal can handle high speed runout or pressurized chemicals. It utilizes press-in fitment for open seal housing. This seal design eliminates spring dumping, and provides protection for the sealing lip during installation. It can be retrofitted to replace standard seals.

R2R2
R2 – Spring-loaded double-lip oil seal
Spring-loaded double-lip rotary shaft seal with non-metallic reinforcing element.
Used for oil and grease retention.
The optimized seal lip design uses a stainless steel garter spring to maintain a constant radial lip load, thus ensuring optimum sealability. The non-metal reinforcement element ensures concentric fitment and increased corrosion resistance over traditional shaft seals. The secondary lip acts as a dust wiper for light dirt and fluid exclusion and lube retention. This style is available in a wide range of elastomers and small quantities for repairs and seal replacement and can be shipped in1 to 3 days.

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.

SFSF
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.
