POM Idler Pulley for GT2 6mm Belt with Bearing for 3D Printer. It is made up of delrin. Delrin is a type of POM. Further, it has many application.
Process to achieve good tension:
By moving the tensioner idler, the tension in the belt can be varied to achieve a good compromise between adherence between the belt and the pulleys in the system and wear on the various bearings.
By using a single, wider belt instead of multiple, thinner belts, the belt may be put under increased tension without stretching. As a result of higher tension reduces slip, which increases belt life and mechanical efficiency.
