Frequently asked questions
Which belt works with this pulley?
Use GT2 belts with 2 mm pitch and at least 6 mm width, such as the 160-2GT-6 closed loop belt.
Will the 8 mm bore fit a NEMA 17 motor shaft?
No. Most NEMA 17 motor shafts are 5 mm, so the 8 mm bore needs an 8 mm shaft or a suitable adapter.
