20T 5mm Bore Dual Ball Bearing Idley Pulley for 6mm GT2 Belt CNC and 3D Printers
20T 5mm Bore Dual Ball Bearing Idley Pulley for 6mm GT2 Belt CNC and 3D Printers
This pulley works with 6mm wide GT2 2mm pitch timing belt, it will work perfectly with GT2 pulley-belt sets we are selling in our store. This idler is a good match to 20T GT2 timing belt pulley driven by stepper motor.
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 M5 screw to mount this pulley.
