3D Maker World GT2 Belt & 20-Tooth Pulley Set 3d printers accessory

SKU CH-G1RH-9S0KZ

GT2 timing belt and 20-tooth aluminium pulley kit for 3D printer motion systems

  • Precise motion control with GT2 2 mm pitch profile
  • Strong, stretch-resistant belt from neoprene with fiberglass reinforcement
  • Lightweight aluminium pulley reduces moving mass for faster prints
  • 582-tooth belt gives 1164 mm (45.83 in) of travel length
  • 5 mm bore with M4 set screws fits common motor shafts

GT2 Timing Belt & Pulley Set

This set supplies one GT2 timing belt and one 20-tooth GT2 timing pulley for 3D printer motion systems. The belt uses neoprene reinforced with fiberglass and the pulley is machined from aluminum. Both components share a 2 mm pitch and 6 mm belt width for direct compatibility. The kit is intended for builders upgrading or repairing linear-drive mechanisms.

Sustained Load Behaviour

The fiberglass reinforcement inside the neoprene belt resists stretch over long print runs, keeping tooth engagement consistent. Aluminum pulley teeth maintain their profile without the wear seen on plastic alternatives. Two M4 set screws lock the 5 mm bore to a motor shaft, preventing slippage during repeated acceleration cycles. The 582-groove belt length supports extended axis travel without joining sections.

GT2 Pitch & Width Limits

The 2 mm pitch and 6 mm width define the maximum torque the pair can transmit without skipping. A 5 mm bore diameter restricts the set to stepper shafts of that exact size. The 1164 mm pitch length fixes the centre-to-centre distance achievable in a given frame. Builders needing a different bore, width or longer belt must source separate components.

Questions about this item

Does the GT2 belt or 20-tooth pulley generate noticeable noise or heat during continuous printing?

The neoprene belt and aluminium pulley are passive mechanical parts; they produce no heat and only the normal meshing sound of a 2 mm pitch GT2 drive.

What must I already have to install the 5 mm bore pulley and 6 mm wide belt?

You need a stepper or idler shaft of 5 mm diameter, a 2 mm hex key for the two M4 set screws, and a printer frame that accepts a 1164 mm pitch-length belt.

Will the 2 mm pitch GT2 belt and 20-tooth pulley work with my older printer that uses the same pitch?

Yes, any system designed for 2 mm pitch GT2 profile and 6 mm belt width will mesh correctly with the 582-groove belt and 20-tooth pulley.
