Step-Down Rotary Shafts
A shoulder near the end of the shaft provides a stop for gears, sprockets, and bearings. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to tight diameter and straightness tolerances.
1045 carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use. They are stronger than aluminum and stainless steel shafts but not as corrosion resistant. 303 stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine.
