Ball screws are widely used in high-end machine tools, aerospace, robots, electric vehicles, 3C equipment and other fields. CNC machine tools are the most important users of rolling components, accounting for 54.3% of the downstream application pattern. With the transformation and upgrading of the manufacturing industry to digitalisation and intelligence, the application of robots and production lines is growing rapidly. Other major end-users accounted for a balanced, diversified and expanding applications in various fields of the machinery industry. Ball Screws are used in the field of robot joints, which can support robots to complete movements quickly and accurately. Ball screws are inherently strong, for example, with a diameter of only 3.5 mm, they can push loads of up to 500 lbs and perform movements in the micron and submicron range, which better mimics the movement of human joints. Higher force-to-size and force-to-weight ratios allow robots to perform motions quickly and accurately, increasing efficiency and precision, while high-precision ball screws provide high-precision and high-repeatability motion control for precise and stable robot movements.
In robot joints, ball screws can be driven in a four-link pattern. The planar four-bar mechanism is composed of four rigid members linked by low vice links, and each moving member moves in the same plane, and the types of mechanisms include crank rocker mechanism, hinged four-bar mechanism, and double rocker mechanism. In order to reduce leg inertia and improve the physical position of the actuator, ball screws are driven using a four-link method, connecting the corresponding actuator to the knee, ankle, and other kinematic joints.
The global ball screws market continues to expand due to increasing demand for high precision. With the upgrading and transformation of the manufacturing industry, the ball screw market demand continues to expand, especially in robotics, aerospace and other high-end applications are expected to continue to expand, and the domestic ball screw industry also continues to develop. 2022 global ball screw market size is expected to be about 1.86 billion U.S. dollars (about 13 billion yuan), with a compound annual growth rate of 6.2% from 2015-2022; 2022 Chinese Ball Screws market size is expected to be about 2.8 billion yuan in 2022, with a CAGR of 10.1% from 2015 to 2022.
& Global Ball Screws Industry Market Competition
CR5 is more than 40%, and the concentration of the global ball screws market is relatively high. The global ball screw market is mainly monopolised by well-known enterprises in Europe, America and Japan, with NSK, THK, SKF and TBI MOTION as the main manufacturers. These enterprises have rich experience and core technology in the design and manufacture of ball screws, and occupy most of the global market share.
With the entry of many domestic enterprises, the breakthrough of domestic ball screws is expected to accelerate. At present, the new domestic enterprises continue to expand the linear actuator, linear motion components and other product investment, and actively research and development of precision ball screw products and core technology.
