Why the TC profile is so widely used
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.
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.
