HTD circular tooth Synchronous pulley Profile classification: HTD2M type, HTD3M type, HTD5M type, HTD8M type, HTD14M type, HTD20M type
HTD circular tooth Synchronous 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 tooth Synchronous pulley surface treatment: natural oxidation, blackening, zinc plating, color zinc plating, high frequency quenching and other treatment. Accuracy level depends on customer requirements.
1, our factory production of HTD circular tooth Synchronous pulley for the domestic equipment of HTD circular tooth Synchronous belt supporting, but also can replace the imported HTD circular tooth Synchronous pulley use.
2, user customized HTD circular tooth Synchronous pulley, please provide pulley drawing (the drawing can not draw the tooth shape size of the pulley), our factory can also draw pulley drawing according to the specifications provided by the user, the inner hole of the pulley, the keyway, the width and other dimensions for the user.
3, our factory HTD circular tooth Synchronous pulley can be processed according to user needs, and our factory can also develop drawings for users.
