The 5mm Aluminum Timing Pulley (Pair) is an 20 tooth timing pulley with a center diameter of 5mm, this is the size you need for mounting on a stepper motor. These pulleys are great for many mechanical projects. They are also very commonly used in 3D printers.
Pleased with the purchase and would recommend these pulleys.
5mm Aluminum Timing Pulley by DFRobot I purchased these to replace another manufacturer's timing pulleys that I had problems with due to stripped threads. Although these pulleys are also made out of aluminum the set screws seems to have more stock to grip on and hopefully will last longer. So far, I am pleased with the purchase and would recommend these pulleys.
