Why the TC profile is so widely used
Its TC construction pairs a rubber-covered OD (a snug press-fit in the bore) with a spring-energised sealing lip and a separate dust lip, so both oil retention and contamination exclusion are covered.
Material: NBR – Nitrile
Nitrile rubber (NBR) is the workhorse of oil sealing: fully compatible with mineral oils, lubricating greases and common hydraulic fluids — the media found in most gearboxes and motors. Avoid contact with brake fluid, and keep spares shaded from sunlight.
It is normal for a shaft to measure a few tenths of a millimetre smaller than nominal; the sealing lip is engineered to take up that difference.
