The 20x35x12 mm Oil Seal 20x35x12 NBR TC keeps lubricant circulating where it belongs — inside the housing — on the 20 mm shafts and 35 mm bores typical of micro motors, angle grinders, cooling pumps and compact gear reducers.

Inside the TC double-lip design
TC is the standard rotary-shaft profile for good reason: a rubber OD seals the bore side, a spring-loaded lip seals the shaft side, and a dust lip extends service life in dirty environments.
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.
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.
