Pulley Type

GT2 Timing Pulley (Synchronous Wheel / 2GT)

Tooth Profile

Rounded tooth profile (optimized for reduced backlash and smoother engagement)

Tooth Pitch

2mm (the distance between the centers of two adjacent teeth)

Number of Teeth

30 Teeth

Belt Width Compatibility

Designed for 6mm wide GT2 timing belts

Bore Diameter

5mm (inner diameter, for mounting on a 5mm shaft, common for NEMA 17 stepper motors)

Outer Diameter (OD)

Approximately 21.4mm - 22mm (based on standard calculations for 30 teeth, 2mm pitch)

Overall Height/Length

Approximately 17.5mm - 21.5mm (can vary slightly by manufacturer based on hub design)

Material

High-Quality Aluminum Alloy (offers good balance of strength, lightweight, and durability)

Flanges

Dual flanges (to keep the belt properly aligned and prevent it from slipping off)

Shaft Fixing

Typically secured by 2 x M3 or M4 grub (set) screws (usually included with the pulley)

Precision

High precision, low backlash, suitable for accurate linear motion and positioning applications. Larger number of teeth generally leads to smoother motion and less "ripple" than smaller pulleys.

Weight

Lightweight, typically around 10g - 15g

Color

Silver (standard for aluminum pulleys)

Typical Applications

3D printers (often for extruder drives or where higher resolution/smoother movement is desired), CNC machines, laser engravers, robotics, automation equipment, and any application requiring precise, non-slipping, and synchronized power or motion transmission.

Compatibility

Compatible specifically with GT2 timing belts (2mm pitch)
