The Oil Seal 50x80x12 NBR TC (50x80x12 mm) renews the sealing on a 50 mm shaft where grease or oil must stay in and grit must stay out — a typical fitment in industrial gearboxes, conveyors and mid-size rotating equipment.

Why the TC profile is so widely used
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) is the standard compound for general industrial sealing. It handles mineral oils, greases and hydraulic fluids, which is why it is the default choice in gearboxes, electric motors and pumps. Keep it away from brake fluid, and store spare seals out of direct sunlight.
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.
