The Oil Seal 25x58x10 NBR TC (25x58x10 mm) renews the sealing on a 25 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.

Why the TC profile is so widely used
TC seals work with a triple defence — a rubber-coated case seating tightly in the bore, a main lip held against the shaft by a garter spring, and an outer dust lip that keeps abrasive particles away.
About the NBR nitrile compound
NBR (Nitrile) is the standard compound for general industrial sealing. It handles mineral oils, greases and hydraulic fluids, which is why it is the default choice in gearboxes, electric motors and pumps. Keep it away from brake fluid, and store spare seals out of direct sunlight.
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.
