Rotary Shafts
Rotary Shafts Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, ground, and polished to meet tight diameter and straightness tolerances.
Steel shafts are generally stronger than stainless steel shafts but not as corrosion resistant. 1566 carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use. 12L14 carbon steel shafts have a lead additive that makes them easier to machine than any other rotary shaft but also more prone to wear. Black-oxide 1045 carbon steel shafts have a black-oxide coating for mild corrosion resistance. Chrome-plated 1045 carbon steel shafts have a 0.0001"-0.0005" thick layer of chrome plating on the outside of the shaft that provides wear resistance and some corrosion resistance. Nitride-coated 1045 carbon steel are the most corrosion resistant steel shafts. 4140 alloy steel shafts are for high-load applications. They have the highest yield strength of any steel shaft; however, they are more difficult to machine than carbon steel shafts.
Stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine. 303 and 440C stainless steel shafts have good corrosion resistance. 316 stainless steel shafts have excellent corrosion resistance.
Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.
