The Oil Seal 58x85x10 NBR TC is a TC rotary shaft seal sized 58x85x10 mm (ID × OD × width). It keeps oil inside and dirt outside on a 58 mm shaft seated in a 85 mm bore — a size common in industrial gearboxes, conveyors and mid-size rotating equipment.

How the TC design works
The TC arrangement — rubber-covered case, garter-spring main lip, external dust lip — is the industry’s go-to solution wherever a shaft spins in an oil-filled housing.
About the NBR nitrile compound
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.
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.
