The Oil Seal 40x60x8 NBR TC (40x60x8 mm) renews the sealing on a 40 mm shaft where grease or oil must stay in and grit must stay out — a typical fitment in motor shafts, gearbox input stages, centrifugal pumps and tillers.

About the TC profile
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.
Why NBR for this seal
NBR nitrile rubber gives the lip its resistance to mineral oils, greases and hydraulic fluids — exactly the fluids a gearbox or pump seal meet. It is the industry’s general-purpose choice; just keep it clear of brake fluid and direct sun when storing.
Measuring your shaft a few tenths under the nominal figure is expected; the spring-loaded lip is built to seal with that small interference.
