The Oil Seal 45x85x8 NBR TC (45x85x8 mm) renews the sealing on a 45 mm shaft where grease or oil must stay in and grit must stay out — a typical fitment in large reducers, belt-conveyor pulleys, slurry pumps and construction machinery.

About the TC profile
The TC arrangement — rubber-covered case, garter-spring main lip, external dust lip — is the industry’s go-to solution wherever a shaft spins in an oil-filled housing.
About the NBR nitrile compound
The compound is NBR nitrile, selected for oil-and-grease compatibility across motors, reducers and pumps. Note the limits: brake fluid degrades nitrile, and sunlight ages stored rubber — so store spares dark and dry.
Measuring your shaft a few tenths under the nominal figure is expected; the spring-loaded lip is built to seal with that small interference.
