Choose the Oil Seal 55x68x10 NBR TC when a 55 mm shaft in a 68 mm housing needs a reliable double-lip barrier. Its 55x68x10 mm size is a regular in mining conveyors, industrial reducers, mixer shafts and rolling equipment.

How the TC design works
Its TC construction pairs a rubber-covered OD (a snug press-fit in the bore) with a spring-energised sealing lip and a separate dust lip, so both oil retention and contamination exclusion are covered.
Material: NBR – Nitrile
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.
