The Oil Seal 25x52x10 NBR TC (25x52x10 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 electric motors, gearboxes, pumps and agricultural machinery.

How the TC design works
Every TC seal combines three elements: a rubber-covered case that grips the bore, a spring-loaded sealing lip that follows shaft runout, and a dust lip that shields the main lip from contamination.
Why NBR for this seal
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.
