Engineered as a direct replacement, the Oil Seal 27x47x7 NBR TC (27x47x7 mm) seals 27 mm shafts against dust and moisture from the moment it seats in the 47 mm bore — common in drive motors, planetary gearboxes, irrigation pumps and feed mixers.

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
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.
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.
