-Idler Pulley for applications such as 3D printers.
-Uses larger internal bearings for much higher reliability over the other idler pulleys you can find in this size.
(I have > 230 days or 5500 hours on 5 Flying Bear Tornado 3d printers without a single bearing failure, where with the standard available idler pulleys i would expect to experience a bearing failure every 100-200 hours of printing).
-Able to handle higher tension belts which enables higher speed printing without ringing.
-CNC machined & assembled in St. Louis, USA; bearings are relatively high quality made in China 11mm bearings with 5mm bore.
-1 year warranty (this is just to cover random flaws, I seriously doubt that any of these will fail, allow I will probably cover them for longer, I just don’t want to get into a position where I no longer have a way to manufacture these and still have to cover warranty)
-I can provide engineering drawings if needed, but the only change is that they use larger higher quality bearings.
