Ball screw is the most commonly used transmission component in tool machinery and precision machinery. Its important feature is to convert rotary movement into linear motion, or to convert torque into axial repeated force. At the identical time, it has the traits of high precision, reversibility and high efficiency. Because of its low friction resistance, ball screws are extensively used in quite a number industrial equipment and precision instruments.

The high efficiency of lead screw bearing is vastly superior to conventional screws. The torque required is much less than 30%. Linear motion can be easily changed from rotary motion.very stringent quality control standards covering every production process. With proper lubrication and use, trouble-free operation for an extended period of time is possible.

Ball screw is made of screw, nut and ball. The function is to flip the rotary motion into liner motion, which is a similarly extension and development of ball screw. The value of this development is to go into a rolling bearing from sliding action; With little friction, ball screws are widely used in various industrial tools and precision instruments.

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

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

Ball screws and lead screws are mechanical linear actuators that are commonly used to translate rotary motion into linear motion and are usually used in CNC machines.
All screws serve the same motive of converting rotary motion into linear motion, they have distinct differences in their design, performance, and suitability for different types of applications.
Ball screws employ recirculating ball bearings to reduce friction and increase efficiency, whereas lead screws make use of helical threads and a nut to produce linear movement.
Lead screws are metal bars with threads as that of a traditional screw, and the relative motion between the screw and nut reasons the linear movement of the latter.

Ball screw is made of screw, nut and ball. The function is to turn the rotary movement into liner motion, which is a similarly extension and development of ball screw. The significance of this development is to move into a rolling bearing from sliding action; With little friction, ball screws are widely used in various industrial equipment and precision instruments.

Ball screws are machine elements that convert the rotational motion of a motor, etc., into linear motion. Major functions consist of transportation and positioning of merchandise and parts, semiconductor manufacturing equipment, industrial robots, and machine tools. Since the amount of travel (lead) per revolution of a ball screw can be precisely reproduced, high positioning accuracy can be achieved by combining it with a stepping motor.

In NC-controlled computing device tools, ball screws are used to configure the feed mechanism and obtain precision positioning accuracy. Ball Screws are additionally used in food machinery, medical equipment, robots, injection molding machines, printing equipment, amusement equipment, automobiles, trains, aircraft, semiconductor manufacturing equipment, and inspection equipment.

Kairun precision ground ball screw that achieves low noise, small torque fluctuations and long-term maintenance-free operation by using a ball cage. Using a screw shaft ground to high accuracy. In the DIN standard compliant ball screw, balls below a load roll in the raceway reduce between the screw shaft and the nut whilst receiving the axial load, travel along the groove of a deflector embedded inside the nut to the adjoining raceway, and then circulate back to the loaded area. Thus, the balls perform infinite rolling motion.

Precision ground DFU series is a highly advanced and innovative product that has been designed to meet the needs of contemporary industries. These precision floor DFU series are engineered with the latest technology and are of the perfect quality. They have been constructed to supply the best performance in phrases of accuracy and precision.

The ball screw is composed of a screw rod, a nut, a steel ball, a pre-compression piece, a steering gear, and an anti-skid piece. Its characteristic is to convert rotary motion into linear motion, and the important significance of its development is to transform the bearing from sliding motion into rolling motion. Ball screws are widely used in a number industrial gear and precision instruments because of their low frictional resistance. Transmission aspects frequently used in machine tools and precision machinery, whose important feature is to convert rotary motion into linear motion, or the rotor into axial repetitive force, and have the characteristics of high precision, reversibility, and high efficiency. Now we mainly introduce the type of ball screws .

Because the ball screw uses ball motion, the starting torque is extremely small, and there will be no crawling phenomenon like sliding motion, which can ensure the realization of accurate micro feed. Ball screw has the traits of high lead precision and exact sensitivity. When synchronous transmission is required, various units of ball screw pairs with the same lead can be used to acquire exact synchronization performance. The hardness of the ball and raceway can reach HRC58~63. The shape of the raceway is accurate, the rolling friction and wear are very small, and it has good accuracy retention, reliability and service life.

Feature of rotating nut ball screw: High efficiency of transferring, smooth movement, high precision, duration, reliability, no hole and preloading, low friction, lengthy lasting design and high-speed operation.
