8mm Bore Aluminum Timing Pulley for 3D Printers, 5mm Pitch HTD5M, 14 Teeth, 15mm Wide Belt Groove, Two Set Screws to Secure to Stepper Motor, High Precision Synchronous Drive Wheel

8mm Bore Aluminum HTD5M Timing Pulley for 3D Printers
✔️ 8mm bore, 5mm HTD5M pitch, 14 teeth, 15mm wide, single pulley

Designed for HTD5M belt systems in 3D printers and compact CNC setups, this aluminum timing pulley combines durable construction with precise engagement. It fits an 8mm shaft and uses two set screws to lock firmly in place for reliable, slop-free operation. Commonly used in RepRap, Kossel Delta, and other small printers and machines.

✅ 8mm bore fits standard 8mm shafts
✅ 5mm HTD5M belt pitch matches HTD5M belts in 14-tooth pulleys
✅ 14 teeth balance speed, torque, and belt engagement
✅ 15mm wide belt groove supports common HTD belts
✅ Two set screws secure shaft mounting for a solid drive

💡 What is a timing pulley used for in belt-driven systems such as HTD5M belt drives?

This handy overview explains the core role in motion control for 3D printers and small CNCs. - Transmits rotation to belt to drive motion with precision - Maintains timing between motor, belt, and driven pulley - Optimizes compatibility with 5mm pitch HTD5M belts and 14-tooth pulleys
