Product Description
Single lip, spring-loaded design
Rubber cover over metallic core for an excellent combination of sealing ability and corrosion resistance
Most economical general purpose seal type
The rubber elastomer outer covering tolerates thermal expansion as well as roughness in the housing bore
Because of the rubberized covering on the seal, there will be no fretting/galvanic corrosion of the metal bore that the seal is pressed into
With only one sealing lip, this seal can either retain lubricant or exclude contaminants but cannot do both simultaneouslyThe nitrile seal offers good resistance to standard oils, greases, and normal fuelsThis material also provides good abrasion resistanceFollow this link for access to Timken's interactive, multi-vehicle, bearing & seal application database.
