Oil and grease seals from Timken feature precision sealing designs to prevent lubricant escape and stop harmful contaminants from entering. Vent holes allow lubricants to flow freely around the seal lip, cooling seal components and removing heat build-up.
Did not fit my 1979 Datsun 620 pickup. It was slightly too big. I bought two of them and was unable to get either one to fit. I managed to find a couple CR INDUSTRIES CHICAGO RAWHIDE OIL SEALs PN 21041. They fit perfectly.
The seals were good quality, but were listed as fitting my truck when they did not fit.
