Replace the worn seal on a 20 mm shaft with the Oil Seal 20x32x10 NBR TC — 20x32x10 mm, TC profile, NBR compound — it drops into a 32 mm bore and stops the leak. Popular in light-duty motors, drills, mini pumps and small gearbox assemblies.

How the TC design works
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.
Material: NBR – Nitrile
This is an NBR-nitrile seal — the everyday elastomer for oil-lubricated equipment, compatible with mineral oils, greases and hydraulic media. For longest life, avoid brake fluid contact and store spares away from direct 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.
