HTD circular arc tooth synchronous belt gear tooth classification: HTD2M, HTD3M, HTD5M, HTD8M, HTD14M, HTD20M
HTD circular arc tooth synchronous belt pulley Raw materials: generally made of steel, aluminum alloy, cast iron, brass, and other materials. The inner hole has round hole, D-shaped hole, conical hole and other forms.
HTD circular arc tooth synchronous belt wheel surface treatment: natural oxidation, blackening, zinc plating, color zinc plating, high-frequency quenching and other treatment. Accuracy level depends on customer requirements.
1. The HTD circular arc tooth synchronous belt produced by our factory is not only a matching set for the HTD circular arc tooth synchronous belt of domestic equipment, but also can replace the imported HTD circular arc tooth synchronous belt.
2, user customized HTD circular arc tooth synchronous pulley, please provide pulley drawings (it is not necessary to draw the tooth shape size of the pulley in the drawing), our factory can also draw pulley drawings according to the specifications provided by the user, the inner hole of the pulley, the keyway, the width and other dimensions.
3, our factory HTD circular arc tooth synchronous belt wheel can be processed according to user needs, and our factory can also develop drawings for users.
