Made in the U.S.A,  NB’s shafts are never anneal, so outer diameters are ultra precise – tolerances are always reliable. Tapped shaft can be ordered with one or both ends tapped in either case-hardened carbon steel or stainless steel. Threaded shaft can be ordered with one or both ends threaded in case-hardened carbon steel. Diameters range from ¼” to 1-1/2”. Travel lengths sections available from 6” to 36”.

Guaranteed diameter tolerance of ISO g6 and straightness tolerances of 0.001” to 0.002” per foot. The case hardened steel, precision ground shafts have a 10-16rms micron finish. Case hardness is Rockwell C60-C64.

NB's engineering expertise encompasses a wide range of manufacturing and machining capabilities for linear shafting, bearing rails and other equipment components. With sophisticated machinery, industry-leading quality control processes and a history of innovation dating back to 1939, they can meet requirements for accuracy, toughness and precision.

NB eliminated the difficulties customers encounter with precision machining threads and bevel ends in case hardened shaft. Choose the diameter and standard travel length you need and they’ll ship your 52100 steel shaft. 440 stainless steel is also available by quote.
