Engineered as a direct replacement, the Oil Seal 45x70x10 NBR TC (45x70x10 mm) seals 45 mm shafts against dust and moisture from the moment it seats in the 70 mm bore — common in steel-plant gearboxes, screw conveyors and big-bore rotating shafts.

How the TC design works
As a TC-pattern seal it seals in two stages: a primary spring-loaded lip holds the oil film on the shaft, while a second lip fends off dust and water spray; the rubber-covered case keeps the whole unit anchored in the bore.
NBR nitrile rubber at a glance
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.
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.
