Often used in industrial settings for a wide range of applications, keyed shafts are commonly found in machines and motors, or in gear-and-pulley systems. In key-based engineering, the keyed shaft works in unison with a rotating machine element, allowing for axial movement between parts. Keyed shafts come in a wide variety of lengths, diameters and materials, so determine your preferences before you shop. In addition to keyed shafts, Zoro offers Woodruff keys, shaft collars and a host of couplings as well. You can also shop for shaft adapters and motor parts.
