Adding linear rails to a length of aluminium extrusion is a common way to make a fairly rigid guiding structure, and I have been doing just that in the workshop. But things were not working quite ...

Design refinements boost performance of self-aligning ball bushing while maintaining their error-correcting nature.

The BGS04 linear-rail system handles high moment loads. Its roll, pitch, and yaw-moment load capability lets it maintain tight accuracy and repeatability, even for applications requiring cantilevered ...
