Toothed Idler Pulley (3mm Bore / 20 Tooth / 6mm GT2 Belt)

An idler pulley is used to support movement and change direction of a taught timing belt. All timing belts must operate under tension and this tension is maintained by the idler pulley. Used extensively on 3D printers and other CNC machines, this idler pulley can be mount in various ways to suite your design. It is perfect for 6mm timing belt and includes two pressed bearings with a 3mm bore to support low friction movement.

Two flanged lips on either side of the GT2 tooth profile face ensure that the timing belt stays on its path. The aluminium construction offers a lightweight and durable solution to your timing belt linear motion system.
