Ball screws are force and motion-transfer devices in the family of
power-transmission screws. They operate like conventional power
screws but the rolling friction of bearing balls replaces sliding
friction. Ball screws consist of a screw, nut, and balls that operate
similarly to bearing components.
Ball screw can be classified by different index, such as type of nuts,
direction of pitch, flange, precision class, model, preload types, etc.
Ball screws are mainly used for semiconductor and LCD production
equipment, machine tools and injection molding machines, engraving
Equipment, medical equipment and laboratory equipment, etc.
