One 55x75x10 mm part does the sealing: the Oil Seal 55x75x10 NBR TC wraps a 55 mm shaft in its spring-loaded lip and presses firmly into a 75 mm bore — the kind of fit seen across mining conveyors, industrial reducers, mixer shafts and rolling equipment.

Inside the TC double-lip design
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
Nitrile rubber (NBR) is the workhorse of oil sealing: fully compatible with mineral oils, lubricating greases and common hydraulic fluids — the media found in most gearboxes and motors. Avoid contact with brake fluid, and keep spares shaded from sunlight.
Measuring your shaft a few tenths under the nominal figure is expected; the spring-loaded lip is built to seal with that small interference.
