This aluminum timing pulley is designed for belt-driven motion in 3D printers and other small automation setups. It matches 3mm HTD3M belts and mounts on a 6mm shaft, secured with two set screws for reliable drive.

✅ 6mm bore fits standard stepper motor shafts with set screws
✅ 24 teeth with HTD 3M pitch for reliable belt engagement
✅ 15mm wide belt groove compatible with HTD3M belts
✅ Aluminum alloy provides light weight and stiffness for precise motion

💡 What is a timing pulley used for in a 3D printer belt drive system?

In simple terms, a timing pulley transfers rotary motion to linear motion with precise timing to keep belts aligned and prevent slip.

- Drives HTD3M belt for accurate positioning - Keeps motor and driven axis in sync under load - Reduces belt slip and wear in fast moves - Ideal for compact printers and small CNCs
