Upgrade Your 3D Printer With This 2Pcs 50 Tooth 8mm Bore Timing Pulley And Two Long 1220mm GT2 Belts For Smooth High Speed Printing Action

Dual 50 Tooth 8mm Bore Timing Pulley Set With 1220mm Belts
✔️ 2x pulleys 50 teeth 8mm bore includes durable 6mm width belts

This mechanical kit upgrades the motion transfer system in your 3D printer to reduce wobble. You will typically find this pair of rubber belt timing components installed on the X or Y axis rails where precision alignment is required. It helps achieve higher print speeds without sacrificing layer accuracy.

✅ Includes 50 tooth profile compatible pulleys with 8mm shaft hole
✅ Belt width measures 6mm and total length is 1220mm per strand
✅ Simple installation replaces worn stock hardware for smoother tracking
✅ Heavy duty rubber construction resists stretching during high speed runs

💡 Why do timing pulleys and belts improve 3D printer stability?

Precision gearing ensures the stepper motor turns exactly how many steps are commanded by the software control board. If belts are loose the machine fails to return to start coordinates accurately leading to Z drift errors on the final object surface.
- Matching belt pitch keeps tension consistent across long travel distances
- Proper bore size matches existing motor shaft diameter for secure fastening
- Rubber material absorbs vibration preventing layer shifts during rapid movement
