This TC oil seal measures 30x55x8 mm and is machined for a 30 mm shaft rotating inside a 55 mm housing — a dimension you will meet in motor shafts, gearbox input stages, centrifugal pumps and tillers.

How the TC design works
The TC layout brings three protections together: a rubber outer surface that grips the housing bore, a garter-spring lip that tracks slight shaft movement, and a secondary dust lip that blocks grit before it reaches the sealing edge.
Material: NBR – Nitrile
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.
