Smooth Idler Wheel Kit 5mm Bore


This is double bearing, Delrin, smooth idler wheel. It uses (2) 5×16×5 bearings and a precision shim washer. This is perfect for adding an adjustable idler wheel to your system. It has very low runout, so it will run wobble free. The mating bracket is very simple with only a 5mm hole required. This is a part of the omni-drive system.

The idler wheel diameter does not usually need to match your drive pulley diameter. The belt can run a triangle or more complicated path as long as one side is parallel to the axis you are driving.
