The Oil Seal 26x42x10 NBR TC is a TC rotary shaft seal sized 26x42x10 mm (ID × OD × width). It keeps oil inside and dirt outside on a 26 mm shaft seated in a 42 mm bore — a size common in electric motors, gearboxes, pumps and agricultural machinery.

About the TC profile
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.
Material: NBR – Nitrile
The compound is NBR nitrile, selected for oil-and-grease compatibility across motors, reducers and pumps. Note the limits: brake fluid degrades nitrile, and sunlight ages stored rubber — so store spares dark and dry.
Should the shaft read slightly below the listed size — typically a few tenths of a millimetre — no concern: the lip’s interference fit accounts for it.
