High Performance Linear Ball Screw Transmission Machinery
SEXGL ground ball screws deliver unparalleled accuracy and durability in high-precision automation systems, trusted by global leaders like BYD (EV powertrain assembly) and BOE (LCD panel cutting robots) across North America, Europe, Southeast Asia, and South Korea.As a core transmission component for CNC machine tools, precision instruments, and automation equipment, ball screws achieve high-precision linear motion through a rolling friction pair design: precision balls fill the helical raceways between the screw shaft and nut, converting traditional sliding friction into point/line contact rolling friction with a friction coefficient as low as 0.0015–0.002. This enables positioning accuracy of ±0.001mm over 300mm and repeat positioning accuracy of ±0.0005mm, ensuring micron-level precise displacement for moving components such as machine tool worktables and tool holders. These capabilities meet the stringent requirements of high-precision machining scenarios in aerospace, optical components, and other industries.
