High precision ball screws Internal Circulation Series adopts an internal ball recirculation structure, with balls circulating through built-in channels in the nut, resulting in a compact and lightweight design. This integrated layout minimizes radial space occupation and reduces overall size, making it ideal for space-constrained applications. Ball screw for cnc machine delivers high positioning accuracy and low noise operation due to stable internal ball movement and reduced external interference. With excellent dynamic performance and smooth motion transmission, it is widely used in precision instruments, semiconductor equipment, medical devices, and small to medium-sized automated systems, supporting high-precision motion control in compact scenarios.
