If your 62 mm shaft is weeping oil, the Oil Seal 62x80x8 NBR TC — a TC spring-loaded seal at 62x80x8 mm — restores the barrier between the 80 mm housing and the outside world. A staple size for heavy-duty gearboxes, conveyor drums and large pump shafts.

Why the TC profile is so widely used
TC seals work with a triple defence — a rubber-coated case seating tightly in the bore, a main lip held against the shaft by a garter spring, and an outer dust lip that keeps abrasive particles away.
Why NBR for this seal
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.
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.
