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.
Stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine. 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.

Linear Motion Shafts
Smooth, hard, and wear resistant, linear motion 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. The smooth surface reduces friction and wear on the bearing—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. 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. 17-4 PH stainless steel shafts have excellent corrosion resistance and high yield strength to support heavy loads.
Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.
Hardened shafts are heat treated for increased wear resistance.

Dowel Pins
Use dowel pins as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. For a tight fit, your hole should be equal to or slightly smaller than the diameter shown. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
Steel pins are the strongest dowel pins. Steel pins are precision ground except for 1/32" diameter pins. Stainless steel pins are more corrosion resistant than steel pins. Pins that are passivated offer added protection against corrosion and oxidation. Stainless steel pins are precision ground except for 1/64" diameter pins. 18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic. 416 stainless steel pins are more wear resistant than other stainless pins, but not as corrosion resistant. They are magnetic.
Pins that meet ASME B18.8.2 specifications conform to ASME standards for material and dimensions, and pins that meet MS16555 specifications conform to military standards for material and dimensions.
