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.

Aluminum shafts are a lightweight, corrosion-resistant option for use with linear sleeve bearings. They have a thin, ultra-hard coating that provides additional wear resistance. Because they have a soft core they are not for use with linear ball bearings, which may dent the shaft. Anodized 6061 aluminum shafts have a higher yield strength than ceramic-coated 6061 aluminum shafts, which means they handle heavier loads. Ceramic-coated 6061 aluminum shafts are good for use in harsh environments; a 0.002" thick ceramic coating prevents weld spatter, molten glass, and paint from sticking to the shaft.

Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.

These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating. Shafts have a smooth surface to reduce friction and wear on linear bearings—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. They are case-hardened to increase hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to tight diameter and straightness tolerances.

One-piece shafts reduce vibration and assembly time. Ceramic-coated 6063 aluminum shafts are good for use in harsh environments; a 0.002" thick ceramic coating prevents weld spatter, molten glass, and paint from sticking to the shaft. They are lighter in weight than steel and stainless steel shafts. Because they have a soft core they are not for use with linear ball bearings, which may dent the shaft.
