Timing Belt:

Highest quality precision timing belt, not cheap Chinese replacement. Made from NEOPRENE - Synthetic Rubber reinforced with fiberglass cords for superior strength. Neoprene - oil-resistant substitute for natural rubber, was invented by DuPont scientists on April 17, 1930. Balanced combination of polymer's properties:

  • Resists degradation from sun, ozone and weather
  • Performs well in contact with oils and many chemicals
  • Remains useful over a wide temperature range
  • Displays outstanding physical toughness
  • Resists burning inherently better than exclusively hydrocarbon rubbers
  • Outstanding resistance to damage caused by flexing and twisting


  • Belt Material: Neoprene (Synthetic Rubber)
  • Belt Type: GT2 / P2M
  • Pitch (mm): 2
  • Belt Width (mm): 6
  • Core Wire Material: Glass Fiber
  • Circumference Length (mm): Open Loop
  • Number of Teeth: N/A
  • Belt Shape: Open End
  • Belt Tooth Surface: Standard (Single Sided)
  • Belt Shape Type: Round Tooth Profile High Torque

Filament Pulley:

Bronze filament pulley for 3d Printer. Fits Nema 17 Stepper Motor with 5mm shaft. 2 grub screws. Very sharp teeth.
This drive gear works with both 1.75mm and 3mm ABS and PLA filaments.
