One 17x40x10 mm part does the sealing: the Oil Seal 17x40x10 NBR TC wraps a 17 mm shaft in its spring-loaded lip and presses firmly into a 40 mm bore — the kind of fit seen across household appliance motors, power tools, aquarium pumps and small gear drives.

Why the TC profile is so widely used
Three features define the TC type: the rubber outer case that fills small bore imperfections, the garter-spring-loaded lip that maintains contact under runout, and the auxiliary lip that acts as a dirt barrier.
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.
Should the shaft read slightly below the listed size — typically a few tenths of a millimetre — no concern: the lip’s interference fit accounts for it.
