Multi-wedge pulley

Product listCixi Xinlong synchronous belt pulley Co., LTD

Multi-wedge gear tooth type classification: PH type, PJ type, PK type, PL type, PM type

Multi-wedge pulley Raw materials: Generally made of steel, aluminum alloy, cast iron, brass, etc. The inner hole has round hole, D-shaped hole, conical hole and other forms.

Multi-wedge pulley surface treatment: natural oxidation, blackening, zinc plating, color zinc plating, high-frequency quenching and other treatment. Accuracy level depends on customer requirements.
