The number of starts influences the load capacity, stiffness, and efficiency of the screw drive. A higher number of starts can improve load distribution and increase the system’s service life. At the same time, it can reduce friction and wear.
Single-start screw drives are easy to manufacture due to the single thread start. They offer high precision and are therefore ideal for applications that require accurate positioning.
Multi-start screw drives are characterized by several parallel thread starts, enabling them to carry higher loads. They are more efficient and, due to a higher lead per start, offer higher travel speed, which qualifies them for applications with high requirements for speed and load capacity.
