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.
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.

Easy-Access Base-Mounted Shaft Supports
These two-piece supports allow access to the shaft without needing to slide out the shaft or uninstall the support. All are lightweight, corrosion-resistant aluminum. Use them to brace the end of a linear shaft when working with light to medium loads where shaft alignment is not critical. Tighten the included clamping screws to secure.

Machinable Easy-Access Base-Mounted Shaft Supports
Create a support that fits the exact dimensions of your shaft. Good for use with square- and hex-profile shafts, these aluminum supports also work with round shafts of any diameter up to 1". Use them for light-to-medium-load linear motion applications where shaft alignment is not critical. Supports come with spacers between the two halves. For a snug fit, leave the spacers in place when machining, then remove before installing the shaft.

Support-Rail Shafts
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.

Low-Profile Support Rails
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).

Keyed Rotary Shafts
Combine these shafts with a machine key (not included) to transmit torque to gears, sprockets, and other power transmission components. All have an ANSI standard keyway (keys not included; see our selection of key stock). Their 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.
2024 aluminum shafts are a lightweight, corrosion resistant, and nonmagnetic. They have a T4 temper, which means they have been heat treated for increased strength.
