Ball Screw is a mechanical device that converts rotational motion to linear motion. It consists of a Ball Screw shaft and a Ball Screw nut that contains a series of ball bearings. As the screw shaft rotates, the ball bearings move along the groove in the ball screw nut, causing the nut to move linearly along the axis of the screw.
Ball Screw are commonly used in applications that require precise linear motion, such as CNC machines, robotics, and aerospace systems. They offer high accuracy, high efficiency, and low friction, making them ideal for demanding applications where reliability and performance are critical. High-precision Ball Screw are used in applications that require precise positioning and repeatability, such as in CNC machines, robotics, and aerospace equipment.

A Ball Screw is a mechanical device used to convert rotary motion into linear motion. It is a type of screw mechanism that consists of a threaded shaft (screw) and a nut with ball bearings. The screw is typically driven by a motor, and as it rotates, the ball bearings inside the nut move along the threads, causing the nut to move linearly along the screw.
The design of a linear ball screw allows for high precision and efficiency in converting rotational motion into linear motion. The ball bearings reduce friction between the screw and the nut, resulting in smoother movement and improved overall performance.

High mechanical efficiency. VXO Ball Screw are fitted with steel Balls, providing rolling contact between the Nut and Screw Shaft, allowing for mechanical efficiency of over 90% and reducing the required Torque to less than one-third that of conventional Lead Screws. The design of the KSS Ball Screws also allows linear motion to be converted into rotary motion easily.
Axial play. Without conventional Triangular and Trapezoidal Screw threads, reducing the Axial play increases the rotational Torque due to the sliding friction.
VXO Ball Screw, on the other hand, are very easily rotated, even with no Axial play. The use of Double Nuts also provides increased Rigidity.
High precision. VXO Ball Screw are machined, assembled, and inspected using the technology of ultra-precision Lead Screw and Screw Gauge maching, under the temperature controlled room. High precision and accurate positioning ensure high reliability in use.
Long service life. The Ball Screw movement results in virtually no wear, as the rolling-contact design, combined with the use of carefully selected heat-treated materials, results in an extremely low friction. This is the reason that high precision can be kept over long period.
A Ball Screw is a mechanical device that converts rotary motion into linear motion. It consists of a screw shaft and a ball nut that contains a series of recirculating ball bearings. The screw shaft has a helical groove that runs along its length, while the ball nut has internal grooves that match the helical groove on the screw shaft.
When the screw shaft rotates, the ball bearings in the ball nut are forced to roll along the helical grooves, causing the ball nut to move linearly along the screw shaft. This linear motion can be used to move a load or to position a tool or machine component.
Supplied by the reliable linear motion bearing manufacturers, the ball bearings in the ball nut are designed to recirculate within the nut, which allows for high efficiency and accuracy in the motion transmission. The design also allows for high speeds and long travel distances without significant wear on the screw and nut components.
Overall, the ball screw is a highly efficient and precise mechanical device that is commonly used in applications such as CNC machines, robotics, and aerospace equipment.
1. High Efficiency: Ball screws have a very high level of efficiency, typically between 90-95%. This means that the amount of input torque is effectively converted into linear motion parts, resulting in less energy loss and higher overall efficiency.
2. High Precision: Ball screws such as double ball screws are designed to provide high precision linear motion. They have a very low friction coefficient, which means that there is minimal backlash or play in the system. This makes them ideal for applications where accuracy and repeatability are critical.
3. Low Maintenance: Ball screws require very little maintenance. They are self-lubricating and can operate for long periods without needing any additional lubrication. This reduces downtime and maintenance costs.
4. High Speeds: Ball screws such as bidirectional ball screws are capable of high-speed operation, making them ideal for applications where high-speed linear motion is required.
5. High Load Capacity: Ball screws including heavy duty ball screw can handle high loads, making them ideal for heavy-duty applications. They are capable of carrying loads that are much higher than other types of linear motion systems.
6. Quiet Operation: Ballscrews operate quietly, making them ideal for applications where noise levels need to be kept to a minimum.
7. Long Life: Ball screws have a long service life, typically lasting for many years. This reduces replacement costs and downtime.
There are two types of ball screw nut circulation systems:
1. Endcap return system: In this type of system, the ball screw nut is equipped with endcaps that have channels for the balls to circulate through. The balls travel from one endcap to the other through the channels, creating a continuous loop. This rolled thread ball screws system is simple and cost-effective, but it has a limited speed and load capacity.
2. Internal circulation system: In this type of system, the ball screw nut has internal channels for the balls to circulate through. The channels are usually curved, which allows for a smoother and more efficient circulation. This system can handle higher speeds and loads, but it is more complex and expensive to manufacture.

A recirculating ball screw is a mechanical device used to convert rotational motion into linear motion. It consists of a threaded shaft and a nut that contains a series of ball bearings. The ball and roller bearing circulate through the nut as the shaft rotates, allowing the nut to move linearly along the shaft.
The recirculating ball screw works by using the ball bearings to reduce friction between the shaft and nut. As the shaft rotates, the ball bearings roll along the threads of the shaft and nut, creating a smooth and efficient motion. The ball bearings are held in place by a retainer, which ensures that they remain in contact with the threads of the shaft and nut.
The linear movement of the nut can be controlled by the rotation of the shaft. By controlling the speed and direction of the shaft, the linear movement of the nut can be varied. This makes recirculating roller screw ideal for use in a wide range of applications, including machine tools, robotics, and automation systems.
Overall, the recirculating ball screw is a highly efficient and reliable device for transmitting linear movement. Its ability to reduce friction and provide precise control over linear motion makes it an essential component in many industrial and mechanical systems.
