Why the TC profile is so widely used
TC seals work with a triple defence — a rubber-coated case seating tightly in the bore, a main lip held against the shaft by a garter spring, and an outer dust lip that keeps abrasive particles away.
Why NBR for this seal
Made of NBR (acrylonitrile-butadiene rubber), the seal tolerates the mineral oils and lithium greases that lubricate most machinery. Standard practice: keep NBR away from brake fluid, and store unused seals in their bag, 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.
