About the TC profile
As a TC-pattern seal it seals in two stages: a primary spring-loaded lip holds the oil film on the shaft, while a second lip fends off dust and water spray; the rubber-covered case keeps the whole unit anchored in the bore.
Why NBR for this seal
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.
Measuring your shaft a few tenths under the nominal figure is expected; the spring-loaded lip is built to seal with that small interference.
