Description: Pillow block bearing mounts attach to the outside of a channel and can be used as simple hinges. These bearing mounts have a width of 1.32”, a thickness of 0.25”, a 0.25” bore bearing.

Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.


  • Width - 1.30”

Customer Comments

  • I have a DC motor with a coupler to extend the shaft (not far, couple inches). I’d like to stabilize the shaft and place it in a bearing. How do you ensure the shaft is attached to the bearing so it’s not just spinning inside the bearing bore?

    Sorry if my terminology is off, not totally sure how to even ask my question.

  • Is there any product link for the shaft or screw that connect the pillow block? Whats the name of that shaft or screw?

  • I got a few set of these to mount a pinion gear to my project. Two of these where ok but on two of them the bearings were too tight and did not spin freely. I think these parts may work well to hing two channels together or something, but I ended up using an other piece of channel and two flanged bearing to hold the a spinning shaft.

These bearings are exactly what I needed. I did a lot of searching for something like them and did not have much luck until I came here. Price is excellent! Shipping is very timely. I could not have asked for more. Thanks!

As expected

Aluminum bearing - dimensions as expected - this is an entry level, low load pillow block. Seems fine.
