Large Diameter Steel Shafts


A shaft diameter categorizes large diameter shafts as 5" or greater. We supply a range of large-diameter steel shafts from 5" in diameter up to 30". Our high-quality steel shafting is designed for heavy-duty industrial-grade applications that demand the most from a steel shaft. We offer shafting as plain, keyed full length (or specific key placement), stress-proof, and turn ground and polished (TGP) for precision applications. Our material selection consists of C1018 steel, 1045-steel, and 303-grade stainless steel (special order specific materials available on request). We also supply these large diameter shafts in particular lengths, eliminating costly and unwanted drops and a range of large diameter shaft collars! For additional information or to get a quote on shafting and other components, contact our customer support team, and we will be happy to assist you!
