Hella Durable Black Aluminum Timing Pulley With 80 Teeth And Single Bore Groove Ready To Amp Up Your 3D Printer Setup With Rock Solid Precision And Faster Speeds

Single Pack 80 Tooth V Belt Drive Sprocket Unit
✔️ Black anodized aluminum 80 tooth single groove drive unit

This eighty tooth timing pulley converts rotational motor power into reliable linear motion for DIY 3D printers and CNC routers. You mount this single included piece on stepper motors or engine crankshafts to synchronize belt movement across light fabrication workshops and small scale machine shops.

✅ Eighty evenly spaced teeth maintain exact belt tracking ratios
✅ One solid hole accepts common 5mm to 12mm drive shaft widths
✅ Hard oxidized surface resists corrosion and daily grinding wear
✅ Lightweight alloy build lowers spin inertia for quicker acceleration

💡 How does picking a matched drive sprocket improve stepper motor performance? This handy hardware component locks down critical timing geometry so your belt moves without slipping or stretching prematurely. - Lock set screw alignment with hex keys before powering the axis - Pair pitch ratio correctly with microstepping driver settings - Route timing belts clear of frame brackets during full extension - Clean mounting holes with acetone to prevent shaft wobble stress
