SHAFTING

When selecting shafts, consider diameter and straightness tolerances. Ensure uniform distribution of loads and improve accuracy and repeatability with tighter tolerances.

Hardened shafts are used with linear ball bearings and linear sleeve bearings. All of our hardened shafts have micron finishes that are ideal for linear bearings, slides, and other precision applications. A shaft's finish affects frictional resistance and smoothness of travel as well as the efficiency and life of linear bearings. The lower the micron value, the smoother the finish.

Case hardness is a heat-treating process to harden the outside surface of shafts. Harder shafts provide more wear resistance. The higher the case value, the harder the shaft.

Drive shafts are often used with gears, sprockets, and other power transmission components. Available with ANSI keyways for a secure hold in higher-torque applications. Most shafts are not hardened, for easier machining.
