Self-reversing screws are commonly known as level winder screws.Unlike lead screws or ball screws,which require the screw to reverse rotation direction for the nut to return to its starting point,a self-reversing screw operates with continuous unidirectional rotation.As the nut reaches one end of the screw,it automatically reverses direction and travels back.
We manufacture custom-made level winder screws based on your drawing or sample.Our reciprocating thread level winder screws have been exported to over 60 countries,delivering high quality while helping clients save at least 30% in costs.
