The global precision ball screw market was valued at $1,571. 0 million in 2019, and is projected to reach $2,043. 9 million by 2027, registering a CAGR of 5. 1% from 2020 to 2027. Precision ball screws are mechanical elements used for transmission of rotational to linear motion. It is an improved version of conventional acme lead screws, in terms of accuracy, precision, and efficiency. It has high efficiency (greater than 90%) in motion transmission as it converts sliding friction into rolling friction. Precision ball screws find extensive applications in the semiconductor industry, medical devices, and aerospace industry, owing to its high load bearing capacity, positional accuracy, and repeatability. In addition, it enables cost and weight savings in overall design of a mechanical system.
