The 30x58x7 mm Oil Seal 30x58x7 NBR TC keeps lubricant circulating where it belongs — inside the housing — on the 30 mm shafts and 58 mm bores typical of electric motors, gearboxes, pumps and agricultural machinery.

Inside the TC double-lip design
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
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.
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.
