Acetal Timing Belt Idler (6mm ID x 12mm OD, 18mm Width, 1-2) - 2 Pack

This timing belt idler is a very compact solution for adding tension to your timing belt assembly.  The inside width was chosen to accept 15mm width timing belts such as our 3mm HTD belts.  The bore provides a slip-fit over a 6mm shaft, standoff or spacer.
