1 Pcs - Idler Pully without teeth 2GT timing pulley with ball bearing for 6mm timing belt Bore 3/5mm OD13/16/18mm

This is a small but crucial part used in 3D printers to guide and maintain the tension of the GT2 timing belts. It features a toothed design that matches the teeth on the belts, ensuring accurate and synchronized movement of the printer's components. The "idler" designation indicates that it's used to route the belt around corners or to maintain tension, rather than being directly connected to a motor. Properly functioning idler pulleys contribute to the printer's overall accuracy and print quality by preventing belt slippage and maintaining proper belt tension.
