Why the TC profile is so widely used
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 rubber gives the lip its resistance to mineral oils, greases and hydraulic fluids — exactly the fluids a gearbox or pump seal meet. It is the industry’s general-purpose choice; just keep it clear of brake fluid and direct sun when storing.
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.
