1/4" Bore Ball Bearing Tube Roller, Acetal

This tube roller makes for a clean and compact idler setup. With pre-installed 1/4” ID ball bearings, this tube roller is ready to slide onto a 1/4” shaft and start rolling! The contoured shape of the tube roller allows it to self-center when running on a tube or shaft with an outside diameter of 1/4” up to 2”. The overall width is 1.195” so that it can be mounted on an aluminum standoff and installed inside the Actobotics® channel. To hold the bearings away from the inside wall of the channel, a 1/4” plastic spacer should be installed on each side of the tube roller.
