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: 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.
Measuring your shaft a few tenths under the nominal figure is expected; the spring-loaded lip is built to seal with that small interference.
