The T2.5 Series of belts and pulleys will significantly increase your RepRap print quality. Our T2.5 pulleys are made from aluminium and suitable for our 6mm T2.5 belt which is made from fibre glass reinforced polyester rubber.
For optimal performance you ideally want at least 6 teeth in contact with the pulley at all times, this means at minimum a 12 toothed pulley. Our T2.5 pulleys have 16 teeth giving an excellent reduction in backlash but also keeping torque and print resolution high.
