Lead screws and ball screws require the driven screw to change its direction of rotation in order for the nut to return to its original starting position.In contrast,a self-reversing screw operates with continuous unidirectional rotation.The reciprocating bidirectional movement is achieved by using a pawl(follower blade)inside the nut,which is matched to the specific groove width.As the nut reaches one end of the screw,it automatically reverses direction and travels back.
Self-reversing screws offer significant advantages in applications requiring continuous,high-frequency reciprocating motion where frequent motor starts,stops,and direction changes are not permitted.By eliminating the need for direction-changing controls,limit switches,and complex electrical control logic,they ensure continuous and smooth operation without directional impact or backlash errors.This not only enhances equipment stability and durability but also simplifies the structure and reduces costs,making them a more efficient and reliable choice for high-frequency reciprocating drive systems.
LMT specializes in the manufacture of self reversing screws with outer diameters ranging from 5 mm to 150 mm.We manufacture self-reversing screws and diamond screws to your exact specifications,from materials and dimensions to surface coatings—all customized based on your technical drawings.
