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.

Base-Mounted Shaft Supports
For use with light to medium loads where shaft alignment is not critical, these shaft supports brace the end of a linear shaft along the ground or other flat surface. Slide the shaft in to install, then tighten the included clamping screw to secure.
Aluminum shaft supports are lightweight and corrosion resistant. Iron shaft supports are heavier than aluminum shaft supports for a more stable mount.

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.

Flange-Mounted Shaft Supports
Made of lightweight, corrosion-resistant aluminum, these shaft supports hold linear shafts perpendicular to the mounting surface. Use with light to medium loads where shaft alignment is not critical. Loosen the clamping screw to install, then tighten to secure.

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).

Support Rails
Support rails 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).

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. Two-piece shafts allow you to replace the shaft when it becomes worn.
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.
Carbon steel shafts are stronger than aluminum shafts but not as corrosion resistant. 1055 carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use. 1566 carbon steel shafts have a higher yield strength than 1055 carbon steel shafts for supporting heavier loads.
440C stainless steel shafts have good corrosion resistance and high yield strength, which allows them to support heavy loads.
