With self-reversing screw,only one direction of rotation is required to achieve reciprocated bi-directional lateral movement.The reciprocated bi-directional movement is achieved by using a follower blade in the nut,that is matched to the particular groove width.A crisscross thread pattern allows you   Read More>

ALM is known for manufacturing different types of lead screws,like trapezoidal lead screw,ACME screw,metric thread screw and reciprocating screws.To meet customer's application requirements of higher precision and higher smoothness.ALM introduced a top-tier round thread lead screw series.Round threa   Read More>

A lead screw is a type of screw used to convert rotational motion into linear motion.It consists of a threaded shaft (also known as a screw)and a nut that has corresponding threads.When the lead screw is rotated,the nut moves along the threads,resulting in linear motion.The self-locking property of   Read More>

Trapezoidal lead screws are widely used in various industries, including automotive, aerospace, and medical equipment. These lead screws are known for their high precision and accuracy,making them an essential component in many critical applications. However, to enhance their performance and durabil   Read More>

The factors influencing the efficiency of the trapezoidal screw include the following points:1. Pitch Angle (Thread Rise Angle)The pitch angle is the inclination angle of the screw helix line, determined by the pitch and the diameter of the screw. A larger pitch angle leads to higher transmission ef   Read More>
