A ball screw is also called a ball bearing screw or recirculating ball screw. It is a mechanical linear actuator that translates rotational motion to linear motion with little friction. It consists of a screw spindle, a nut, balls, and an integrated ball return mechanism.
Ball screws are used in aircraft and missiles to move control surfaces and in automobile power steering to translate rotary motion from an electric motor to axial movement of the steering rack. They are also used in machine tools, robots, and precision assembly equipment.

Ball bearing type screws are found in the Steering mechanism.
The steering mechanism in vehicles is responsible for controlling the direction of movement. It allows the driver to steer the vehicle in the desired direction by turning the steering wheel. Ball bearing type screws are commonly used in the steering mechanism to ensure smooth and efficient operation.
Reasons for using ball bearing type screws in the steering mechanism:
1. Reduced friction: Ball bearing type screws incorporate ball bearings between the screw threads and the nut. These ball bearings reduce friction during the movement of the screw, allowing for smoother rotation. This is especially important in the steering mechanism, as it requires quick and precise movements.
2. Improved efficiency: Due to the reduced friction, ball bearing type screws offer improved efficiency compared to traditional screws. This means that less effort is required to turn the steering wheel, resulting in a smoother and more responsive steering experience for the driver.
3. Increased durability: Ball bearing type screws are designed to handle heavy loads and repeated use. They are built to withstand the forces and vibrations experienced in the steering mechanism, ensuring long-lasting performance and reliability.
4. Enhanced precision: The ball bearings in these screws provide a high degree of precision in the steering mechanism. This allows for accurate and consistent steering control, ensuring that the vehicle responds as intended.
5. No backlash: Backlash refers to the free movement or play between the screw threads and the nut. Ball bearing type screws have minimal or no backlash, which means that there is no delay or slack in the steering response. This is crucial for maintaining control and ensuring the safety of the vehicle.
In conclusion, ball bearing type screws are used in the steering mechanism to reduce friction, improve efficiency, increase durability, enhance precision, and eliminate backlash. These screws play a critical role in ensuring smooth and precise steering control, providing a safe and comfortable driving experience.
