How the TC design works
The TC arrangement — rubber-covered case, garter-spring main lip, external dust lip — is the industry’s go-to solution wherever a shaft spins in an oil-filled housing.
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.
