Engineered as a direct replacement, the Oil Seal 48x75x12 NBR TC (48x75x12 mm) seals 48 mm shafts against dust and moisture from the moment it seats in the 75 mm bore — common in mining conveyors, industrial reducers, mixer shafts and rolling equipment.

About the TC profile
Three features define the TC type: the rubber outer case that fills small bore imperfections, the garter-spring-loaded lip that maintains contact under runout, and the auxiliary lip that acts as a dirt barrier.
Material: NBR – Nitrile
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.
