The outside of these tubes is anodized to improve wear and corrosion resistance. Often called decorative anodize, the coating provides a uniform finish that readily accepts paint and adhesive. More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

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 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.

At approximately one-third the height of standard versions, these rails provide linear shaft support in applications with low vertical clearance. They provide stability over the entire length of shaft and eliminate bending under moderate to heavy loads. Made of lightweight, corrosion-resistant aluminum, they are designed for use with linear shafts and bearings. Cut to size or mount end-to-end to make longer lengths. Mounting holes match those on our Shafts for Support Rails; attach using socket head screws (not included).
