GT3 Timing Pulley 20T -Build your projects with this high-quality aluminum timing pulley! With more aggressive teeth than its little brother the GT2, it's perfect for higher torque applications. It has a 6.35mm bore size which fits the Nema 23 Stepper Motors.

The Belt Mount Plate L Type is an easy way to attach the ends of an open-ended belt to a V-Slot or another t-slot extrusion. To tension the belt, attach one end then tension the belt as a second clip is attached. Using the perpendicular hole, an M5 screw and nut can be used as a tensioner. Both G2T and GT3 belts can be secured using these Belt Mounting Plates.

This pulley is designed to work with 6mm wide GT2 2mm pitch timing belts. It's a perfect match for GT2 pulley-belt sets. The idler is also a good choice for 20T GT2 timing belt pulleys driven by stepper motors.
