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
Material-wise this is NBR nitrile: a balanced compound for mineral oil, diesel-range fuels and greases at moderate temperatures — ideal for rotating equipment. Two cautions: no exposure to glycol-based brake fluid, and keep stock seals out of sunlight.
It is normal for a shaft to measure a few tenths of a millimetre smaller than nominal; the sealing lip is engineered to take up that difference.
