The Oil Seal 32x72x8 NBR TC is a TC rotary shaft seal sized 32x72x8 mm (ID × OD × width). It keeps oil inside and dirt outside on a 32 mm shaft seated in a 72 mm bore — a size common in AC motors, worm gearboxes, gear pumps and harvest machinery.

About the TC profile
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.
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.
Should the shaft read slightly below the listed size — typically a few tenths of a millimetre — no concern: the lip’s interference fit accounts for it.
