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 fracture of trapezoidal lead screws is usually the result of the combined effect of multiple factors. Mainly, it can be attributed to the following five aspects:1. Load and operating conditions (Improper use):1.1. Overload and impact: Exceeding the rated load of the lead screw or experiencing su   Read More>

If the screw rod (such as a ball screw) is not straightened (or is bent and deformed), it will have serious negative impacts on the performance, lifespan and safety of the mechanical equipment, mainly manifested in the following five aspects:1. The positioning accuracy and processing quality will si   Read More>
