The 45x55x8 mm Oil Seal 45x55x8 NBR TC keeps lubricant circulating where it belongs — inside the housing — on the 45 mm shafts and 55 mm bores typical of mining conveyors, industrial reducers, mixer shafts and rolling equipment.

About the TC profile
The TC layout brings three protections together: a rubber outer surface that grips the housing bore, a garter-spring lip that tracks slight shaft movement, and a secondary dust lip that blocks grit before it reaches the sealing edge.
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.
If your shaft measures a few tenths of a millimetre under the nominal size, that is normal — the sealing lip is designed with interference for exactly that.
