About Shafts

Rotary Shafts
Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, precision ground, and polished to meet tight diameter and straightness tolerances. This means these shafts evenly distribute loads, reduce vibration, and improve accuracy and stability.
Steel shafts are generally stronger than stainless steel shafts but not as corrosion resistant. 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 more difficult to machine. 303 stainless steel shafts have good corrosion resistance and are easier to machine than other types of stainless steel. 316 stainless steel shafts are the most corrosion resistant stainless steel shaft.
Shafts with chamfered edges reduce damage to bearings, housings, and other components during installation.

Ball Splines and Bearings
Create a compact linear and rotary motion system for applications requiring complex, fast movements, such as robotics. The grooves on the ball splines transmit rotary power as ball bearings move smoothly and precisely along their length, even at high speeds.
Ball splines are alloy steel for high strength and wear resistance. They're hardened on the outside for additional wear resistance while the center is soft enough to absorb stress from shifting loads.
Bearings have a retaining ring groove, so they can be positioned in your system with a retaining ring (not included). Bearings with a keyway include a machine key for attaching your load. Flanged bearings have a surface with mounting holes for attaching your load. Stainless steel bearings are more corrosion resistant than steel bearings.
