The ball screw is an exceptional fastener, crafted with precision and adorned with a spherical head. This ingenious design typically consists of a rod paired with a screw head, seamlessly arranged in a sequence that includes a hexagonal rod and a thread. Notably, the screw head's spherical architecture offers a superior contact area coupled with universal rotation capabilities. This makes it the ideal solution for mechanical connections requiring adaptable adjustments or supportive structures. The threaded section of the ball screw is generally triangular, crafted from high-quality materials such as carbon steel, stainless steel (like 304/316), aluminum alloy, and copper. A variety of sophisticated surface treatments, including galvanizing, oxidation, and nickel plating, ensure durability and enhanced performance.
Ball screws serve a multitude of applications across various industries. In the automotive sector, they play a pivotal role in lighting dimming systems, using a ball head fixing seat for precise reflector angle adjustments, with the nylon fixing seat minimizing wear. In industrial settings, the spherical end design excels in providing stable connections amidst vibrations, thanks to its multi-directional rotation support. Within the medical realm, hollow ball screws are instrumental in orthopedic applications, facilitating the injection of bone cement for fortified bone fixation. Furthermore, the electronics industry values ball screws for their compactness and flexible adjustability, making them indispensable in the miniaturization processes of electronic equipment assembly.
