About Shafts

Rotary Shafts
Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are precision ground 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. 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. Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.

Splined Shafts for Rotary and Linear Motion
Grooves on the surface of these shafts transmit rotary power while allowing bearings to move freely along the length of the shaft. 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.
Four Splines
Shafts with four splines work with ball spline bearings, which create relatively little friction. They're commonly found in robotic and other automated systems that require complex, fast movements. They don't transmit as much torque as shafts with six splines.
All four-spline shafts are 52100 alloy steel for high strength. They're case-hardened to increase hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads.
