2GT Timing Belt Pulley — Precise 2mm Pitch Drive for 3D Printers & CNC Machines

When your 3D printer skips steps or your CNC router loses position mid-cut, the culprit is often a worn or mismatched timing pulley. Makers, hobbyists, and small-workshop engineers who demand repeatable motion accuracy need a pulley they can trust to mesh cleanly with their 2GT belt every single time.

These 2GT timing belt pulleys feature a 2mm tooth pitch and a 7mm belt-contact width, machined from aluminum alloy. Tooth counts range from 16T to 110T, and bore diameters span 4mm to 25mm (approximately 0.16 in to 0.98 in), covering the most common shaft sizes used in desktop automation and motion-control builds.

Typical use cases include Cartesian and CoreXY 3D printer X/Y axis drives, CNC router spindle-feed assemblies, laser engraver gantry systems, and custom DIY linear-motion rigs where a 2GT belt is already specified.

⚙️ Compatibility: Designed for standard 2GT (GT2) open or closed timing belts with 2mm pitch and 6–7mm width. Verify your shaft diameter before ordering — bore sizes range from 4mm to 25mm across variants.

✅ Key Features of These 2GT Timing Belt Pulleys

🦷Wide Tooth-Count Range (16T–110T)
From compact 16-tooth drive pulleys to large 110-tooth reduction pulleys — one listing covers the full spectrum for your build.
📐2mm Pitch, 7mm Belt Width
Matches the industry-standard 2GT/GT2 belt profile for smooth, low-backlash power transmission in precision motion systems.
🔩Multi-Bore Options (4mm–25mm)
Available in bore diameters from 4mm to 25mm to fit NEMA stepper motor shafts, hobby servo shafts, and custom drive axles.
🏗️Aluminum Alloy Construction
Lightweight yet rigid aluminum body keeps rotational inertia low — critical for fast direction changes in 3D printer and CNC applications.
🔄Set-Screw Bore Retention
Typically includes one or two set screws for secure shaft locking without permanent modification to your drive shaft.
🖨️3D Printer & CNC Ready
Dimensionally compatible with RepRap, Voron, Ender, and most open-frame CNC router designs that use 2GT belt drive systems.

❓ Frequently Asked Questions

How do I choose the right number of teeth for my build?

The tooth count determines your drive ratio and belt loop length. For 3D printer X/Y axes, 16T–20T pulleys are most common on the motor shaft, paired with a larger idler or driven pulley. For CNC reduction drives, match the tooth ratio to your desired speed/torque trade-off. Measure your existing belt loop or calculate the required center distance before selecting.

Which bore diameter should I order for a NEMA 17 stepper motor?

Standard NEMA 17 stepper motors have a 5mm output shaft. Select the 5mm bore variant. If your motor has a D-cut shaft, ensure the set screw aligns with the flat. For NEMA 23 motors, the shaft is typically 6.35mm (1/4 inch) — choose the 6.35mm bore option.

Are these pulleys compatible with GT2 belts?

Yes. The 2GT profile is dimensionally identical to the GT2 profile — both use a 2mm pitch with a rounded tooth form. These pulleys are fully compatible with standard GT2 open-ended and closed-loop timing belts with 6mm or 7mm width.

How strong are aluminum timing pulleys for CNC use?

Aluminum alloy pulleys are well-suited for light-to-medium CNC routing, laser engraving, and 3D printing loads. For heavy-duty industrial applications with sustained high torque, steel pulleys may be more appropriate. For typical desktop CNC and 3D printer duty cycles, aluminum provides an excellent strength-to-weight ratio.

Do these pulleys resist corrosion?

Aluminum alloy naturally forms a protective oxide layer that provides good resistance to light moisture and humidity. For environments with prolonged water exposure or chemical contact, consider applying a light coating of machine oil or selecting an anodized variant if available.

Can I use a 16T pulley as a motor pulley and a 60T as a driven pulley?

Yes. Mixing tooth counts from this range is a common approach for creating reduction drives. A 16T motor pulley paired with a 60T driven pulley gives a 3.75:1 reduction ratio, increasing torque while reducing output speed. Ensure your belt length accommodates the center distance between the two pulleys.

What is the difference between a flanged and non-flanged pulley?

Flanged pulleys have raised edges on one or both sides of the tooth profile to keep the belt tracking on the pulley. Non-flanged (smooth-edge) pulleys are typically used as idlers or in systems where belt tracking is managed by other means. Check the product images or contact us to confirm flange configuration for your selected variant.
