Introducing our High-Quality Ball Screw, a marvel of engineering and precision! This unique fastener boasts a spherical head design, seamlessly integrating a rod and a screw head with a hexagonal rod and sequential thread arrangement. The spherical structure of the screw head offers a substantial contact area and unmatched universal rotation capability, making it the perfect choice for mechanical connections requiring flexible adjustments or robust support. Our ball screws feature a triangular-shaped thread and are crafted from premium materials including carbon steel, stainless steel (304/316), aluminum alloy, and copper. To ensure durability and longevity, they undergo advanced surface treatments such as galvanizing, oxidation, and nickel plating.
Our versatile ball screws are indispensable across various industries, finding applications in automotive lighting dimming systems, mechanical universal connections, and medical devices like orthopedic bone screws. In automotive headlights, they employ a ball head fixing seat to precisely adjust reflector angles, with nylon fixing seats minimizing wear. Industrial applications benefit from the spherical end design, allowing multi-directional rotation and stable connections even in vibrating environments. In the medical realm, hollow ball screws are essential for injecting bone cement, providing enhanced bone fixation. Their compact design and adjustment flexibility make ball screws a popular choice in the miniaturization of electronic equipment assemblies, where precision and adaptability are paramount.
