The Oil Seal 32x55x7 NBR TC (32x55x7 mm) renews the sealing on a 32 mm shaft where grease or oil must stay in and grit must stay out — a typical fitment in industrial motors, speed reducers, hydraulic pumps and farm equipment.

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.
About the NBR nitrile compound
Material-wise this is NBR nitrile: a balanced compound for mineral oil, diesel-range fuels and greases at moderate temperatures — ideal for rotating equipment. Two cautions: no exposure to glycol-based brake fluid, and keep stock seals 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.
