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.
Rectangular supports do not have a mounting flange. They are the most compact support we offer. Mount these supports to a surface from the bottom using the tapped holes.
Aluminum supports are lightweight and resist corrosion.

Base-Mounted Dual Shaft Supports
Secure two linear motion shafts parallel to each other and the mounting surface to build a system that moves smoothly and doesn’t bind. These supports are made of aluminum, so they are lightweight and resist corrosion. They are machined to have flat, square surfaces, so they can be used to align other supports and parts in your system. Slide your shafts into the holes and tighten the clamping screws (not included). The clamping screws also mount the shaft support to your surface, so your surface must have threaded holes.
