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.
NBR nitrile rubber at a glance
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.
If your shaft measures a few tenths of a millimetre under the nominal size, that is normal — the sealing lip is designed with interference for exactly that.
