The 42x85x10 mm Oil Seal 42x85x10 NBR TC keeps lubricant circulating where it belongs — inside the housing — on the 42 mm shafts and 85 mm bores typical of industrial motors, speed reducers, hydraulic pumps and farm equipment.

Why the TC profile is so widely used
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
This is an NBR-nitrile seal — the everyday elastomer for oil-lubricated equipment, compatible with mineral oils, greases and hydraulic media. For longest life, avoid brake fluid contact and store spares away from direct sunlight.
Don’t worry if your micrometer shows the shaft a few tenths under size — the garter-sprung lip is designed to seal against exactly that condition.
