Pack of 10 Aluminum HTD 3M timing belt pulleys for CNC builds
✔️ 100 Tooth synchronous wheel 6mm keyway fits 8 to 28mm shaft bores

This set of ten aluminum alloy synchronizer drives swaps out fried units on open loop motion rigs. You slap these onto stepper motors or spindle shafts to push rotational force straight into matching rubber belts. The baked-on anodized skin fights off shop grease and keeps your rig light when swapping out busted axles or tuning extruders.

✅ 100 precise teeth for slip free power transfer at consistent RPM
✅ 6mm wide keyway slot secures firmly against torque spikes
✅ Adjustable bore options from 8mm up to 28mm for most shaft sizes
✅ Hard anodized exterior protects against corrosion and wear

💡 How does an aluminum timing belt pulley kit improve linear motion stability?
A sync belt drive setup simplifies axis building by removing chain slack adjustments.
- lightweight alloy construction keeps inertia low across rapid start stops
- hard anodized exterior handles shop grime without quick surface replacement
- matched tooth geometry delivers handy reliability when cycling heavy print beds
