Ball screws are a type of mechanical linear actuator. The ball screw consists of a screw and nut with matching grooves and ball bearings that move between them. The unique element of ball screws is the ball bearings, which increase the power efficiency by minimizing the friction during the movement of the ball and nut. ​ The unique element of ball screws is the rolling balls in the helical groove which reduces the mechanical contact inside the screw assembly and replaces sliding friction with rolling friction. This mechanism significantly lessens the friction generated, which results in highly efficient power conversion. The efficiency of screws is measured by their capability to transform power utilized in exerting rotational force to the linear distance covered. Ball screws have more complex structures and components and appear to be bulkier than other types of screws. They are more expensive than other screw types, but their benefits and capability outweigh their cost.

Key Applications of Ball Screw Bearings

• CNC Machine Tools: Provide high rigidity and low backlash in CNC milling, turning, and grinding machines for precision cutting and machining.
• Industrial Robotics: Enable accurate, repeatable movements in robotic arms and linear actuators for tasks like pick-and-place, welding, and assembly.
• Medical Equipment: Deliver smooth, quiet, and precise motion in CT scanners, MRI machines, and surgical robots where accuracy is critical.
• Semiconductor Manufacturing: Ensure vibration-free positioning in wafer handling and processing, safeguarding the integrity of delicate operations in clean rooms.

Characteristics of Ball Screw Bearings

• High Axial Rigidity: Designed with steep contact angles and often paired for greater stiffness, reducing deflection and improving positioning accuracy.
• Low Starting and Running Torque: Precision design minimises friction, reducing energy use, lowering heat, and enhancing efficiency.
• Backlash Elimination: Preloaded configurations remove internal clearance, ensuring zero backlash for accurate CNC and robotics applications.
• High Rotational Velocity: Support heavy axial loads while achieving rapid movement and shorter cycle times in demanding environments.
