One 26x42x7 mm part does the sealing: the Oil Seal 26x42x7 NBR TC wraps a 26 mm shaft in its spring-loaded lip and presses firmly into a 42 mm bore — the kind of fit seen across industrial motors, speed reducers, hydraulic pumps and farm equipment.

Inside the TC double-lip design
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.
NBR nitrile rubber at a glance
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.
Don’t worry if your micrometer shows the shaft a few tenths under size — the garter-sprung lip is designed to seal against exactly that condition.
