If your 42 mm shaft is weeping oil, the Oil Seal 42x52x10 NBR TC — a TC spring-loaded seal at 42x52x10 mm — restores the barrier between the 52 mm housing and the outside world. A staple size for drive motors, planetary gearboxes, irrigation pumps and feed mixers.

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.
About the NBR nitrile compound
NBR (Nitrile) is the standard compound for general industrial sealing. It handles mineral oils, greases and hydraulic fluids, which is why it is the default choice in gearboxes, electric motors and pumps. Keep it away from brake fluid, and store spare seals out of direct sunlight.
Should the shaft read slightly below the listed size — typically a few tenths of a millimetre — no concern: the lip’s interference fit accounts for it.
