国外滚珠丝杠的应用领域有哪些？

Ball screw is a commonly used mechanical component in many industrial applications. Its primary function is to convert rotary motion to linear motion or vice versa. The ball screw consists of a threaded shaft (screw) and a nut with a set of ball bearings between them. The balls circulate between the screw and the nut, reducing friction and providing high precision and accuracy in motion transfer. The global ball screw market is highly competitive and fragmented with a large number of players operating in the market. Some of the key players in the ball screw market include THK, NSK, HIWIN, Bosch Rexroth, Schaeffler, SKF, Kuroda, TBI Motion, NTN, and PMI. The demand for ball screws is driven by various factors such as increasing automation in manufacturing industries, growing demand for precision engineering, and rising investments in the aerospace and defense sector. The automotive industry is also a major consumer of ball screws, as they are used in various applications such as steering systems, braking systems, and powertrain systems. In terms of geography, the Asia Pacific region is expected to dominate the global ball screw market, owing to the presence of a large number of manufacturing industries in the region. North America and Europe are also significant markets for ball screws, driven by the increasing demand for automation and precision engineering in various industries.
