The ball screw, an exceptional fastener, stands out with its distinctive spherical head. Comprising a rod and a screw head, typically featuring a hexagonal rod with a sequential thread arrangement, this unique design offers a larger contact surface and unparalleled universal rotation capabilities. It's the ideal choice for mechanical connections that necessitate flexible adjustment or robust support. The ball screw's threaded section often boasts a triangular contour and is crafted from premium materials such as carbon steel, stainless steel (like 304/316), aluminum alloy, or copper. To enhance durability and performance, the surface can undergo various treatments including galvanization, oxidation, and nickel plating, making it versatile for diverse applications.
Ball screws are indispensable across numerous sectors. In the automotive industry, they are crucial for the precision adjustment of lighting systems, where the ball head fixing seat ensures optimal reflector angle adjustment while the nylon seat minimizes wear. Their spherical end design excels in industrial settings by allowing multi-directional rotation, maintaining stable connections within vibrating environments. In the medical arena, hollow ball screws play a vital role in orthopedic procedures, particularly in the injection of bone cement for superior bone stabilization. Their compact and adaptive design is also highly valued in the miniaturization of electronic devices, allowing for efficient assembly and precise adjustments.
