Made in the U.S.A., NB’s shafts are never annealed, so outer diameters are ultra precise — tolerances are always reliable. Tapped shafts can be ordered with one or both ends tapped, in either case-hardened carbon steel or stainless steel. Threaded shafts can be ordered with one or both ends threaded, in case-hardened carbon steel. Diameters range from ¼ to 1-½ in. and travel length sections are available from 6 to 36 in.
Guaranteed diameter tolerance is ISO g6 and straightness tolerances are 0.001 to 0.002 in. per foot. The case-hardened steel, precision ground shafts have a 10-16 rms micron finish. Case hardness is Rockwell C60 to C64.
Our 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, we can meet your requirements for accuracy, toughness, and precision.
We’ve eliminated the difficulties our customers encounter when precision-machining threads and bevel ends in case-hardened shafts. Choose the diameter and standard travel length you need, and we’ll ship your 52100 steel shaft. 440 stainless steel is also available by quote.
