2GT Timing Belt Pulleys — 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 mismatched or worn timing pulley. Makers, hobbyists, and small-workshop engineers who demand repeatable motion accuracy need a 2GT timing belt pulley that fits their shaft exactly and meshes cleanly with standard GT2 belts — without play, wobble, or slippage.

These 2GT timing belt pulleys feature a 2mm pitch tooth profile machined from aluminum alloy, with a step-flanged body that keeps 6mm-wide GT2 belts tracking straight. Tooth counts range from 14T to 64T (approximately 0.55 in to 2.52 in pitch diameter), and bore options span 3 mm to 25 mm (0.12 in to 0.98 in) to suit a wide range of motor shafts. Two hub styles are available: K-type (standard set-screw hub) for smaller pulleys and BF-type (flanged hub with set-screw) for larger tooth counts requiring extra belt retention.

Typical use cases include GT2 belt drive systems on FDM 3D printers such as Ender, Voron, and CoreXY builds; X/Y-axis drive trains on desktop CNC routers and laser engravers; and lightweight conveyor or indexing mechanisms in educational robotics and automation lab setups where a 2mm-pitch timing belt pulley replacement or upgrade is needed.

✅ Compatible with: Standard 2GT / GT2 open-loop and closed-loop timing belts, 6mm belt width. Fits NEMA 17 motor shafts (5 mm) and common stepper/servo shaft diameters from 3 mm to 25 mm. Verify your shaft diameter and tooth count before ordering.

✅ Key Features of These 2GT Timing Belt Pulleys

⚙️
2mm Pitch GT2 Tooth Profile

Matches standard GT2 / 2GT open and closed timing belts for zero-backlash motion in 3D printers and CNC drives.

📐
Wide Tooth Count Range: 14T – 64T

Choose from 30 tooth-count options to dial in your exact gear ratio, from compact 14-tooth drive pulleys to large 64-tooth idler configurations.

🔩
Multiple Bore Sizes: 3 mm – 25 mm

Available in bore diameters from 3 mm to 25 mm (0.12 in – 0.98 in), covering NEMA 17 (5 mm), NEMA 23 (6.35 mm), and custom shaft sizes.

🏗️
K-type & BF-type Hub Styles

K-type offers a compact set-screw hub for smaller pulleys; BF-type adds a flanged collar for improved belt retention on larger-diameter pulleys.

📏
Step-Flanged Body, 7mm Belt Width Seat

Integrated side flanges keep 6mm GT2 belts centered on the pulley face, reducing belt walk and extending belt service life.

🔧
Aluminum Alloy Construction

Lightweight aluminum alloy body keeps rotating mass low for responsive acceleration in high-speed 3D printer and CNC motion systems.

❓ Frequently Asked Questions

How do I choose the right tooth count for my 3D printer or CNC machine?

The tooth count determines your drive ratio and belt speed. Most FDM 3D printers (Ender, Voron, CoreXY) use 20T pulleys on the motor and a matching 20T idler. If you need a speed or torque change, pair a smaller drive pulley with a larger driven pulley. Select your tooth count from the Models option above, then confirm the pitch diameter matches your design's center-to-center distance.

Which bore size fits a NEMA 17 stepper motor shaft?

Standard NEMA 17 stepper motors have a 5mm output shaft. Select "5mm" in the Bore & Amount option. If your motor has a D-cut shaft, the set screw in the K-type or BF-type hub will lock onto the flat. For NEMA 23 motors with a 6.35mm shaft, choose the 6.35mm bore option.

What is the difference between K-type and BF-type pulleys?

K-type pulleys have a standard cylindrical hub with one or two set screws — compact and suitable for smaller tooth counts (14T–26T) where space is limited. BF-type pulleys feature a wider flanged hub with a set screw, providing a larger clamping surface and better belt retention, making them the preferred choice for larger pulleys (28T and above) or applications with higher belt tension.

Are these pulleys compatible with GT2 closed-loop belts?

Yes. The 2GT tooth profile is dimensionally identical to the GT2 profile, so these pulleys mesh correctly with both open-loop GT2 timing belts and closed-loop GT2 belts. Confirm that your belt's width is 6mm to match the pulley's belt seat.

How strong are aluminum alloy pulleys — will they strip under high belt tension?

Aluminum alloy pulleys are well-suited for the belt tensions typical in desktop 3D printers, laser engravers, and light CNC routers. The tooth profile is machined, not cast, so tooth geometry is consistent. For industrial applications with sustained high loads, verify that the belt tension does not exceed the pulley's rated capacity. The set screw should be tightened with thread-locking compound for best retention.

Can I use these pulleys as idlers (without a motor shaft)?

These pulleys are designed as drive pulleys with a bore for a shaft and set screw. To use them as idlers, you would mount them on a smooth bolt or shaft with a bearing inserted into the bore. Alternatively, consider a smooth (toothless) idler pulley for belt-tensioning positions where you do not want the belt to engage teeth.

What should I check before ordering to ensure the pulley fits my build?

Confirm three things: (1) your belt pitch — must be 2mm GT2/2GT; (2) your belt width — must be 6mm; and (3) your motor or shaft diameter — select the matching bore from the Bore & Amount option. Also verify that the pulley's outer diameter (determined by tooth count) fits within your printer or machine frame clearance.

🛒 Select your Model (tooth count), Type (K or BF), and Bore & Amount above, then add to cart.
