If your 45 mm shaft is weeping oil, the Oil Seal 45x56x10 NBR TC — a TC spring-loaded seal at 45x56x10 mm — restores the barrier between the 56 mm housing and the outside world. A staple size for heavy-duty gearboxes, conveyor drums and large pump shafts.

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.
About the NBR nitrile compound
NBR nitrile rubber gives the lip its resistance to mineral oils, greases and hydraulic fluids — exactly the fluids a gearbox or pump seal meet. It is the industry’s general-purpose choice; just keep it clear of brake fluid and direct sun when storing.
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.
