Pulley Type

GT2 Timing Pulley (Synchronous Wheel / 2GT)

Tooth Profile

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

Tooth Pitch

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

Number of Teeth

30 Teeth

Belt Width Compatibility

Designed specifically for 6mm wide GT2 timing belts

Bore Diameter

8mm (inner diameter of the hole, for mounting on an 8mm shaft, which is common for NEMA 17/23 stepper motors or lead screws requiring more robust connections)

Outer Diameter (OD)

Approximately 21.4mm - 21.5mm (calculated based on 30 teeth and 2mm pitch)

Overall Height/Length

Approximately 17mm - 20mm (can vary slightly based on the manufacturer's hub design)

Material

High-Quality Aluminum Alloy (chosen for its balance of strength, lightweight properties, good machinability, and corrosion resistance)

Flanges

Dual flanges (integrated discs on both sides to guide the belt and prevent it from slipping off)

Shaft Fixing

Typically secured by 2 x M3 or M4 grub (set) screws (usually included and used to clamp the pulley onto the shaft)

Precision

High precision, low backlash, suitable for accurate linear movement and positioning. The 30 teeth provide a good balance between resolution and overall size.

Weight

Lightweight, typically around 10g - 15g

Color

Silver (standard for aluminum pulleys; some may be anodized black)
