Timing Belt Pulley, GT2-6

CAD $3.01

In stock


The GT2-6 pulley is designed to perfectly match the tooth profile of 6mm wide GT2 timing belts.  Each pulley has holes for two M3 set screws (aka grub screws) and twenty teeth.  Each pulley has a 5mm inner diameter, the same size as a NEMA17 stepper motors shaft.

We recommend two set screws for each pulley and a hex key to tighten the set screws on rod in the shaft.  You might also want to file a small flat on the shaft.  the set screws will press on the flat and improving the holding power.
