About the TC profile
Every TC seal combines three elements: a rubber-covered case that grips the bore, a spring-loaded sealing lip that follows shaft runout, and a dust lip that shields the main lip from contamination.
Material: FKM – Viton
FKM (Viton®) keeps sealing where NBR gives up: continuous heat, hot oils, fuels and many aggressive chemicals. It is the right choice near engines, in hot gearboxes and wherever elevated temperature ages ordinary rubber within months. Note that FKM is not recommended for hot water or steam service.
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.
