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.
Hardened shafts are heat treated for increased wear resistance. Case-hardened shafts are hardened only on the surface of the shaft, which increases wear resistance while allowing the center to remain soft for absorbing stresses caused by shifting loads.
