Easy-Access Base-Mounted Shaft Supports
Made with two pieces, these shaft supports secure your shaft parallel to your mounting surface and make it easy to access the shaft without having to slide it out or uninstall the support. Use these supports when working with light to medium loads where shaft alignment is not critical. These supports are machined to have flat, square surfaces, so they can be used to align other supports and parts in your system. Tighten the included clamping screws to secure the shaft.
T-shaped supports have mounting flanges on the side. Mount these supports to a surface from either the top or bottom using the unthreaded holes.
Low-profile T-shaped supports are shorter and narrower than standard T-shape supports, so they are good for tight spaces. Mount these supports to a surface from either the top or bottom using the unthreaded holes.
Aluminum supports are lightweight and resist corrosion. Stainless steel supports resist corrosion better than aluminum supports.

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. They are T-shaped, so the mounting flanges are on the side. Mount the support to a surface from either the top or bottom using the unthreaded holes. Slide the shaft in to install, then tighten the included clamping screw to secure the shaft.
Aluminum supports are lightweight and corrosion resistant. Iron shaft supports are heavier than aluminum shaft supports for a more stable mount.
Machined supports have flat, square surfaces, so they can be used to align other supports and parts in your system.

Machinable Easy-Access Base-Mounted Shaft Supports
Create a support that fits the exact dimensions of your shaft to brace it along a flat surface. 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. These supports are T-shaped, so the mounting flanges are on the side. Mount the support to a surface from either the top or bottom using the unthreaded holes. These supports are machined to have flat, square surfaces, so they can be used to align other supports and parts in your system.
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. Tighten the included clamping screws to secure the shaft.
