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.

Metric End Supports for Lead Screws and Ball Screws
A set of ball bearings reduces friction and secures the end of a ball or lead screw. End supports handle radial loads (perpendicular to the lead screw) and thrust loads (parallel to the lead screw). Note: The end of your ball or lead screw must be machined before installing it into an end support.
