This TC oil seal measures 17x37x10 mm and is machined for a 17 mm shaft rotating inside a 37 mm housing — a dimension you will meet in light-duty motors, drills, mini pumps and small gearbox assemblies.

How the TC design works
Three features define the TC type: the rubber outer case that fills small bore imperfections, the garter-spring-loaded lip that maintains contact under runout, and the auxiliary lip that acts as a dirt barrier.
Why NBR for this seal
Material-wise this is NBR nitrile: a balanced compound for mineral oil, diesel-range fuels and greases at moderate temperatures — ideal for rotating equipment. Two cautions: no exposure to glycol-based brake fluid, and keep stock seals out of sunlight.
If your shaft measures a few tenths of a millimetre under the nominal size, that is normal — the sealing lip is designed with interference for exactly that.
