The Oil Seal 52x62x8 NBR TC is a TC rotary shaft seal sized 52x62x8 mm (ID × OD × width). It keeps oil inside and dirt outside on a 52 mm shaft seated in a 62 mm bore — a size common in large reducers, belt-conveyor pulleys, slurry pumps and construction machinery.

Why the TC profile is so widely used
Every TC seal combines three elements: a rubber-covered case that grips the bore, a spring-loaded sealing lip that follows shaft runout, and a dust lip that shields the main lip from contamination.
NBR nitrile rubber at a glance
NBR nitrile rubber gives the lip its resistance to mineral oils, greases and hydraulic fluids — exactly the fluids a gearbox or pump seal meet. It is the industry’s general-purpose choice; just keep it clear of brake fluid and direct sun when storing.
Measuring your shaft a few tenths under the nominal figure is expected; the spring-loaded lip is built to seal with that small interference.
