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.
About the NBR nitrile compound
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.
