Smooth, hard, and wear resistant, these shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances.
Stainless steel shafts are more corrosion resistant than steel shafts; however, they’re not as hard as steel shafts and can be more difficult to machine.
420 and 440C stainless steel shafts have good corrosion resistance and are harder than 17-4 PH stainless steel shafts, so they better resist wear.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.
