Recirculating ball screws are essential components in a wide range of industries, enabling precise and controlled linear motion. VXO, a leading manufacturer of recirculating ball screws, takes pride in offering an extensive array of these versatile mechanisms, each designed to meet the unique demands of various applications. In this comprehensive discussion, we will explore the different types of recirculating ball screws manufactured by VXO. Additionally, we will delve into their applications across industries, and the advantages that make them a preferred choice for precision machinery, robotics, aerospace, medical equipment, semiconductor manufacturing, and more.
Recirculating ball screws are mechanisms designed to convert rotary motion into linear motion efficiently. They comprise three main components: the screw shaft, ball nut, and a set of ball bearings. The key feature that distinguishes recirculating ball screws from other linear motion mechanisms is their ability to recirculate the ball bearings within the system. This continuous recirculation ensures minimal friction, high efficiency, and precise linear movement.
Recirculating ball screws come in various types, each offering specific advantages and suitability for particular applications. VXO manufactures a diverse range of these ball screws, categorized based on their design and construction methods.

Recirculating ball screws offer a range of advantages that make them the preferred choice for various applications:
High Efficiency
Recirculating ball screws are highly efficient, requiring less torque to achieve linear motion compared to alternative linear motion mechanisms. This efficiency results in smaller motors and reduced energy consumption, making them a cost-effective solution for industries seeking energy savings.
Low Friction
Ball screws operate with minimal friction due to the rolling motion of balls between the screw and nut. This low friction not only contributes to their high efficiency but also reduces wear and tear, leading to longer operational life and lower maintenance requirements.
High Load Capacity
Recirculating ball screws can handle significant loads, making them suitable for applications requiring heavy lifting or high-force transmission. They offer superior load capacity compared to some alternatives like lead screws, making them versatile components in industries with varying load requirements.
Precision and Repeatability
Precision and repeatability are hallmarks of recirculating ball screws. They provide precise and repeatable linear motion, making them ideal for applications where accuracy is crucial, such as machining, robotics, and medical equipment. These ball screws excel in maintaining positional accuracy over time.
Low Maintenance
Due to their design with rolling balls, recirculating ball screws experience reduced wear compared to other linear motion mechanisms. This results in lower maintenance requirements and longer service life, reducing downtime and operational costs for industries relying on their performance.
Recirculating ball screws from VXO are integral components in a multitude of industries, offering precise and efficient linear motion solutions.
