Our steel balls are made of high-quality stainless steel, carbon steel and special alloys, with excellent quality. They are meticulously forged with advanced techniques, featuring precise dimensions, smooth surfaces and consistent roundness.
In the field of bearings, they significantly reduce component friction and ensure smooth operation of various machinery; in the grinding industry, with their high hardness and wear resistance, they efficiently crush materials. In precision instruments, their small size and accuracy facilitate precise operation. They are indispensable in automotive transmissions, machine tool ball screw and valves, etc. Meanwhile, we offer customization services, creating exclusive steel balls according to unique requirements, which are widely applicable in both industrial and consumer fields and are a reliable and high-quality choice.
