For 35 mm shafts turning in 75 mm bores, the Oil Seal 35x75x12 NBR TC (35x75x12 mm, TC type, NBR) provides the tight, spring-assisted seal that drive motors, planetary gearboxes, irrigation pumps and feed mixers depend on.

How the TC design works
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.
Don’t worry if your micrometer shows the shaft a few tenths under size — the garter-sprung lip is designed to seal against exactly that condition.
