SFU ball screws fit for CNC machine tools, electronic equipment, automation equipment, laser equipment, medical devices, and other fields. When using a ball screw, it must have sufficient lubrication. If the lubrication is not enough, it will come into contact with the metal, resulting in increased friction and wear, causing failure or short life.

A ball screw with nut is a mechanical device that converts rotary motion into linear motion. It consists of a screw shaft and a nut that contains a ball bearing system. This type of screw is widely used in quite a number industries, along with manufacturing, automation, robotics, and aerospace.

DFU Ball Screws fit for CNC automation machinery parts, Various industrial equipment and precision instruments. We keep good quality and competitive price to ensure our clients benefit.

What units linear action manipulate aside from the rest? It comes with a plethora of The ball screw consists of a screw and nut with matching grooves and ball bearings that go between them. Its feature is to convert rotary motion into linear motion or convert linear motion into rotary motion. Ball screw is the most in many instances used transmission element in device equipment and precision machinery, and has the traits of high precision, reversibility and high efficiency. Due to its small frictional resistance, ball screws are widely used in a vary of industrial equipment and precision instruments.

Ball screw is an ideal product for changing rotary motion into linear motion, or converting linear motion into rotary motion.
Ball screw is the most often used transmission element in tool machinery and precision machinery. Its main function is to convert rotary movement into linear motion, or to convert torque into axial repetitive force, while having the characteristics of high precision, reversibility and high efficiency. Due to its small friction resistance, ball screw is widely used in various industrial equipment and precision instruments.
Ball screw consists of screw, nut, metal ball, preload plate, reverser and dust collector. Its function is to convert rotary motion into linear motion, which is a further extension and development of Aikem screw. The important significance of this improvement is to change the bearing from sliding motion to rolling motion.

The transmission efficiency is high, the friction loss is small, and the transmission efficiency gate of the ball screw nut pair is 0.85~0.98, which can realize high-speed movement.

Smooth movement without crawling. Due to the small frictional resistance and the extremely small difference between the dynamic and static friction coefficients, the movement is stable and crawling is not easy to occur.

The transmission accuracy is high, and there is no lost motion ball screw pair in the reverse direction. After preloading, the axial gap can be eliminated.

The wear is small, the accuracy is maintained, and the service life is long.

With the reversibility of motion, it can convert rotary motion into linear motion, and it can also convert linear motion into rotary motion, that is, both the screw rod and the nut can be used as the driving part or the driven part.

The ball screw can be preloaded with balls so that there is no " wiggle" between the ball screw and the ball nut. This is particularly desirable in applications where the load on the screw varies quickly, such as machining tools.

Ball screws are used in plane and missiles to go manage surfaces, specifically for electric powered fly by using wire, and in automobile power steering to translate rotary motion from an electric motor to axial motion of the steering rack. Because its small friction drag,They are also used in machine tools, robots and precision meeting equipment. High precision ball screws are used in steppers for semiconductor manufacturing.

Rolled Ball crew consist of a screw spindle and a nut integrated with rolling elements that cycle through a return mechanism. It convert rotary motion into linear motion, and are most regularly used in industrial machinery and precision machines.

Kairun produce comprehensive types with SFU, SFS, SFE, SFY kind, single and double nuts. The ball screw provide smooth movement and low friction which can be supplied quickly from stock, at a lower production cost.

Ball screws are used in aircraft and missiles to move control surfaces, especially for electric fly by wire, and in automobile power steering to translate rotary motion from an electric motor to axial movement of the steering rack.

They are additionally used in machine tools, robots and precision assembly equipment. High precision ball screws are used in steppers for semiconductor manufacturing.

Due to the high mechanical efficiency of ball screws, the torque required to function a ball screw is approximately 30% of traditional screw-driven transmission.

The ball screw is rolling friction, and the trapezoidal screw is sliding friction. The temperature rise of the former is much lower than that of the latter during work, so it can undertake the task of high-speed transmission. Ball screws are more suitable for working in high-speed and high-temperature environments, and most large projects will prefer to use ball screws. The surface damage of rolling friction is much smaller than that of sliding friction. Therefore, when the conditions of cleaning and lubrication are met, the maintenance life of the ball screw is much longer than that of the trapezoidal screw.
