1/4" Bore Set-Screw Tube Roller, Aluminum

The aluminum tube roller is a great way to put your project in motion! It has an overall width of 1.2”, and fits perfectly inside Actobotics® channel using 1/4” ID, 1/2” OD flanged bearings inserted into the 1/2” holes of the channel. The contoured shape of the tube roller allows it to self-center when running on a tube or shaft with an outside diameter of 1” up to 2” (diameters smaller than 1” may contact the 10-32 set-screw). It has a 1/4” bore so that it can be mounted to our 1/4” d-shaft and secured into place using the supplied 10-32 set-screw (requires the use of a 3/32” allen key).
