As products, oil seals may be simply described as devices that close or seal the spaces between stationary and moving components in mechanical equipment -they prevent the lubricant from flowing out.

Oil seals often called grease, fluid or dirt seals are vital components of practically every type of machine and vehicle in operation. These seals fulfill an exacting function – they protect all types of precision constructed, close fitting ball, sleeve and roller bearings.

Oil Seal Function

Oil seals are used wherever shafts rotate and bearings require lubrication. A seal is a barrier with three basic functions:

  • Retaining lubricants and liquids
  • Excluding contaminants
  • Seal or separate dissimilar fluids or gases.

Precision bearings rely on the oil seal to prevent lubricants from escaping the bearings or a specific area. Components of machines rely on the oil seal to prevent abrasives, corrosive moisture and other harmful contaminants from entering the mechanics of the machine. Separation of fluids and gases may completely rely on the seal to prevent intermixture of two different mediums such as lubricating oil and water.

In a typical application, the oil seal is installed adjacent to a bearing, sealing in or sealing out, as necessary, the various liquids, gases or solids encountered by the particular mechanism.

Products we Offer

SC Type

sctype

Single lip, spring-loaded design with inner metal case. Rubber cover O.D. Most economical general purpose seals.

Typical applications: engines, drive axles transmissions, pumps, electric motors and speed reducer.

TC Type

tctype

Double lip, spring-loaded design with inner metal case. Rubber cover O.D. Provides light dirt exclusion on the second lip profile, retaining spring-loaded on the main lip.

Typical applications: engines, drive axles transmissions, pumps, electric motors and speed reducer.

VC Type

vctype

Single lip, no spring, rubber covered O.D., improves sealing ability at the housing, and is kind to softer materials.  This type is for non-pressure applications only.

Typical applications: Ideal for grease retention or contamination exclusion.

SB Type

sbtype

Single lip, spring-loaded, precision ground O.D. with a lead-in chamfer to help ease the installation. Does not have the ability to seal around the O.D. like the rubber-covered seals, and is also not as kind to softer housing materials.

TB Type

tbtype

Double lip, spring-loaded, precision ground O.D. with a lead-in chamfer to help ease the installation. Does not have the ability to seal around the O.D. like the rubber-covered seals, and is also not as kind to softer housing materials.

SA Type

satype

Single lip, spring-loaded, precision ground O.D. with the addition of an inner case that provides increased structural rigidity and durability. This style is more often used in large-bore diameters or heavy-duty applications.

TA Type

tatype

Double lip, spring-loaded, precision ground O.D. with the addition of an inner case that provides increased structural rigidity and durability. This style is more often used in large-bore diameters or heavy-duty applications.
