For 30 mm shafts turning in 58 mm bores, the Oil Seal 30x58x10 NBR TC (30x58x10 mm, TC type, NBR) provides the tight, spring-assisted seal that drive motors, planetary gearboxes, irrigation pumps and feed mixers depend on.

Why the TC profile is so widely used
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.
NBR nitrile rubber at a glance
Nitrile rubber (NBR) is the workhorse of oil sealing: fully compatible with mineral oils, lubricating greases and common hydraulic fluids — the media found in most gearboxes and motors. Avoid contact with brake fluid, and keep spares shaded from sunlight.
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.
