Review on πŸ”§ WINSINN GT2 Idler Pulley Pack of 5 - 20 Toothless 5mm Bore Aluminum Timing Pulley Wheel for 3D Printer by Kelly Noonan

Revainrating 1 out of 5

Extremely poor quality Bearings

I can't believe I did myself a disservice by purchasing these parts. I'm causing an unknown problem on my printer with poor print quality until I realize I'm having a lot of vibration from these GT2 idler pulleys. The bearing was so bad it looked like it was made out of a square bearing and not a round one. Also, the rim wobbles a lot, causing the belt to move up and down. Out of 10 I bought only 1 seems to spin smoothly but not perfectly. Folks, before you put these things in your car, be sure to bolt them down and see if they turn smoothly.

Pros
  • Pulleys and pulleys
Cons
  • Available in black only
