Aluminum GT2 Timing Idler Pulley For 6mm Belt 20 Tooth 5mm Bore – 2Pcs

DescriptionType: Timing Idler Pulley – This pulley doesn’t have teeth on its outer surface; it’s designed to guide and support the timing belt (GT2) without driving the motion directly.Compatibility: Designed for GT2 timing belts, which are widely used in 3D printers and other CNC machines. The 6mm refers to the width of the timing belt it’s compatible with.Tooth Count: 20 Tooth – This indicates the number of teeth around the perimeter of the pulley. In this case, it has 20 teeth.Bore Size: 5mm Bore – This refers to the diameter of the hole in the center of the pulley. In this case, it has a 5mm inner diameter (bore), allowing it to fit on a 5mm shaft or motor spindle.Material: Aluminum – The pulley is made of aluminum, which is lightweight and durable. Aluminum is commonly used in these applications due to its strength-to-weight ratio and corrosion resistance.Quantity: 2Pcs – You typically get two pulleys in a set. This is common, especially in applications like 3D printers where multiple pulleys are used for different axes.
