When your 3D printer, CNC router, or automation rig demands repeatable, slip-free motion, the wrong pulley becomes the weakest link in the entire drive system. Engineers and makers who need a 60-tooth 2GT pulley with a 10 mm belt width now have a single, well-documented component that fits without guesswork.
This 2GT timing belt pulley features 60 evenly spaced teeth machined to the GT2 tooth profile, compatible with standard 2GT/GT2 open-ended or closed-loop belts rated for 10 mm width. The bore is available in 5 mm, 6 mm, 6.35 mm (1/4"), 8 mm, 12 mm, and 14 mm to match common motor shaft diameters. The pulley body is typically 38–42 mm in outer diameter and is secured to the shaft via one or two set screws. Material is aluminum alloy with a natural anodized or silver finish for corrosion resistance.
Typical use cases include: DIY CoreXY and Cartesian 3D printer axis drives requiring a 60-tooth reduction ratio; desktop CNC router X/Y gantry systems where low backlash 2GT pulleys improve cut accuracy; and lightweight robotic arm joints or conveyor indexing mechanisms that rely on synchronous belt-and-pulley motion control.
Sixty precisely cut teeth match the 2 mm pitch GT2 belt profile, delivering smooth, low-noise power transmission and minimal backlash across the full speed range.
Available in 5 mm, 6 mm, 6.35 mm, 8 mm, 12 mm, and 14 mm bore diameters to fit NEMA 17, NEMA 23, and other common stepper or servo motor shafts without adapters.
Integrated set-screw hole(s) on the hub allow secure shaft clamping, preventing rotational slip during rapid direction changes in CNC and 3D printing applications.
The flanged rim is sized specifically for 10 mm wide 2GT belts, keeping the belt tracked and preventing lateral drift during high-cycle operation.
Machined from aluminum alloy with an anodized surface treatment, these pulleys resist oxidation and stay dimensionally stable across typical workshop temperature ranges.
Order as a single piece for prototyping or in 5-pack and 10-pack quantities for production builds, machine farms, or spare-parts inventory — all at consistent per-unit specs.

Standard NEMA 17 stepper motors typically have a 5 mm output shaft. Select the 5 mm bore variant for a direct fit. If your motor has a D-shaft, the set screw will lock against the flat for a secure connection.
Yes. The 2GT and GT2 tooth profiles are functionally identical — both use a 2 mm pitch curvilinear tooth form. This pulley meshes correctly with any standard GT2 or 2GT timing belt rated for 10 mm width.
For a 2GT (2 mm pitch) pulley with 60 teeth, the pitch diameter is 60 × 2 mm ÷ π ≈ 38.2 mm. The outer diameter including tooth tips is typically in the 38–42 mm range. Confirm exact dimensions against your design clearance before installation.
Tighten the set screw(s) on the hub against the motor shaft using an appropriate hex key. For D-shaft motors, align the set screw with the flat before tightening. For round shafts, applying a small amount of thread-locking compound to the set screw is recommended for high-cycle applications.
Yes. The 60-tooth count is commonly used on the motor-side drive in CoreXY, Cartesian, and H-bot printer designs where a specific gear ratio or belt path geometry requires a larger pulley. Pair it with a matching 2GT 10 mm belt for best results.
Aluminum alloy pulleys perform well in typical CNC router environments. The anodized surface resists light corrosion and wear from belt contact. For heavy-duty industrial applications with continuous high-load cycles, verify the torque rating against your drive requirements.
Multi-pack quantities reduce per-unit cost and ensure you have matched spares on hand for machine farms, multi-axis builds, or maintenance stock. All pieces in a pack are from the same production batch, so tooth profile and bore dimensions are consistent across units.
