Aluminum Timing Pulley HTD 5M 5mm Bore, 12 Teeth, 15mm Wide Belt Groove, Two Set Screws For Secure Mounting To Stepper Motors, Ideal For 3D Printers And Precision Drive Systems For High Torque Applications And Quiet Operation

Premium 5mm Bore Aluminum Timing Pulley 12T HTD5M, Single
✔️ 5mm bore, HTD5M pitch, 12T, 15mm wide belt groove, 2 set screws

This aluminum timing pulley is a precision-driven drive component for belt-powered motion in hobby 3D printers and small CNC setups. It uses a 5mm bore to fit standard 5mm shaft motors and a 5mm HTD5M belt pitch, with a 15mm wide belt groove for solid belt engagement. Two set screws secure the pulley to the shaft, making it a common fit for delta printers like Kossel and other RepRap-style builds.

✅ 5mm bore fits 5mm shafts for reliable motor coupling
✅ HTD5M pitch ensures precise belt engagement for smooth motion
✅ 12 teeth provide solid torque transfer in compact pulleys
✅ 15mm wide belt groove supports 15mm HTD belts for sturdy grip
✅ Two set screws securely lock to the shaft during operation

💡 What is a timing pulley used for in a 3D printer with HTD5M belts?

A handy explanation helps builders understand its role:

- Maintains precise belt timing for accurate layer deposition
- Enables smooth, repeatable motion by linking motor to the belt
- Works with 5mm shafts and 15mm HTD belts common in RepRap builds
