Description:
This Aluminum GT2 20 Tooth Timing Pulley works with a GT2 6mm wide timing belt, it will work perfectly with the GT2 pulley-belt sets we are selling in our store. This idler is a good match for a 20T GT2 driving Timing Belt Pulley.
Many DIY 3D printer makers are using idler GT2 20 Tooth Timing Pulley based on 3D Printed wheels. An inaccurate printed idler decrease printing quality and creates vibrations since the outside diameter of the idler is not concentric to the rotation axis. Other makers are using double bearings with stationary washers clamped from both sides.
This solution is not ideal since there is friction between the moving belt to the stationary washers. Our Dual BB Aluminum Idler GT2 20 Tooth Timing Pulley is a simple and inexpensive solution to this problem.
Note: These Idler pulleys are used for providing tension in the belt of 3D printers.
