Inside the TC double-lip design
TC seals work with a triple defence — a rubber-coated case seating tightly in the bore, a main lip held against the shaft by a garter spring, and an outer dust lip that keeps abrasive particles away.
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.
