Sized 35x55x12 mm (inner × outer × width), the Oil Seal 35x55x12 NBR TC seals a 35 mm shaft running in a 55 mm bore. This size turns up often in drive motors, planetary gearboxes, irrigation pumps and feed mixers.

How the TC design works
Every TC seal combines three elements: a rubber-covered case that grips the bore, a spring-loaded sealing lip that follows shaft runout, and a dust lip that shields the main lip from contamination.
NBR nitrile rubber at a glance
NBR (Nitrile) is the standard compound for general industrial sealing. It handles mineral oils, greases and hydraulic fluids, which is why it is the default choice in gearboxes, electric motors and pumps. Keep it away from brake fluid, and store spare seals out of direct 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.
