The 45x80x12 mm Oil Seal 45x80x12 NBR TC keeps lubricant circulating where it belongs — inside the housing — on the 45 mm shafts and 80 mm bores typical of large reducers, belt-conveyor pulleys, slurry pumps and construction machinery.

About the TC profile
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
Made of NBR (acrylonitrile-butadiene rubber), the seal tolerates the mineral oils and lithium greases that lubricate most machinery. Standard practice: keep NBR away from brake fluid, and store unused seals in their bag, out of sunlight.
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.
