One 45x90x8 mm part does the sealing: the Oil Seal 45x90x8 NBR TC wraps a 45 mm shaft in its spring-loaded lip and presses firmly into a 90 mm bore — the kind of fit seen across 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.
Why NBR for this seal
The seal lip is moulded from NBR, a nitrile rubber prized for resistance to mineral oil, grease and hydraulic fluids — the default elastomer for general machinery. It should not meet brake fluid, and stored spares fare best away from UV light.
Measuring your shaft a few tenths under the nominal figure is expected; the spring-loaded lip is built to seal with that small interference.
