One 23x40x6 mm part does the sealing: the Oil Seal 23x40x6 NBR TC wraps a 23 mm shaft in its spring-loaded lip and presses firmly into a 40 mm bore — the kind of fit seen across household appliance motors, power tools, aquarium pumps and small gear drives.

Why the TC profile is so widely used
TC is the standard rotary-shaft profile for good reason: a rubber OD seals the bore side, a spring-loaded lip seals the shaft side, and a dust lip extends service life in dirty environments.
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.
