Product Information
Specification

An all-aluminium timing belt pulley for GT2 belt (2 mm pitch) 6 mm wide (up to 6.35 mm wide).

This pulley has 16 teeth and a 5 mm bore.  This is the shaft diameter of a typical NEMA 17 motor.  16 teeth is about the smallest feasible GT2 pulley.  A small pulley gives higher resolution and better mechanical advantage (more force for the same torque) than a larger pulley, at the expense of speed.  Also, a very small pulley like this may wear the belt more than a standard 20-tooth pulley, because the belt curves more sharply around it.

It has two M3 grub screws (at 90° to each other), which require a 1.5 mm hex key (Allen key).  The pulley is 17 mm long overall, has a 13 mm diameter hub, and a flange at the opposite end.  Unlike rubbish aluminium pulleys often found on eBay, which have a flat flange than can chafe the belt, this is a well-made pulley, with an embossed flange, slightly rounded on the side facing the belt, and the hub is also chamfered.
