GT2 20T Aluminum Idler Pulley 3mm Bore

This pulley works with GT2 6mm wide timing belt, it will work perfectly with GT2 pulley-belt sets we are selling in our store. This idler is a good match for 20T GT2 driving timing belt pulley. 

Many DIY 3D printer makers are using idler pulleys based on 3D Printed wheels. Inaccurate printed idler decrease printing quality and create vibrations since the outside diameter of the idler is not concentric to rotation axis. Other makers are using double bearings with stationary washers clamped from both side. This solution is not ideal since there is friction between the moving belt to the stationary washers. Our Dual BB Aluminum Idler Pulley is a simple and inexpensive solution for this problem. Use M3 screw to mount this pulley.

Package contents: 
  • 1 x Aluminum Idler Pulley with dual ball bearings.
