The Oil Seal 60x78x8 NBR TC (60x78x8 mm) renews the sealing on a 60 mm shaft where grease or oil must stay in and grit must stay out — a typical fitment in heavy-duty gearboxes, conveyor drums and large pump shafts.

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.
NBR nitrile rubber at a glance
Nitrile rubber (NBR) is the workhorse of oil sealing: fully compatible with mineral oils, lubricating greases and common hydraulic fluids — the media found in most gearboxes and motors. Avoid contact with brake fluid, and keep spares shaded from sunlight.
Measuring your shaft a few tenths under the nominal figure is expected; the spring-loaded lip is built to seal with that small interference.
