Features and advantages of SBKH series ball screws

The SBKH series ball screw has many significant features and advantages, playing a key role in various fields, mainly reflected in the following aspects:

1. High efficiency

The working principle of the ball screw SBKH series is that the steel ball rolls in the screw thread and nut, reducing friction, so the transmission efficiency is higher.

2. Low friction and long life

The SBKH series ball screw transmits power through rolling friction rather than sliding friction, so it has a lower friction coefficient, reduces energy loss, and has less wear and tear, extending its service life. The rolling friction when the ball contacts the thread generates much less heat than sliding friction and lowers the temperature rise, thus improving its durability and stability.

3. High precision

The SBKH series ball screws can achieve high-precision motion control and are often used in applications that require precise positioning, such as CNC machine tools, precision instruments, etc.

4. Low noise and vibration

The rolling friction characteristics of the ball screw allow it to operate with low noise and vibration. Especially in high-load and high-speed applications, it can effectively reduce the noise and vibration of the mechanical system and maintain the stability and precision of the equipment.

The performance improvement and solutions of ball screw SBKH series 

1. Improve accuracy

By using high-precision processing equipment (such as CNC machine tools, grinders, etc.), it is possible to ensure that the geometry, dimensional accuracy and surface roughness of the screw and ball track reach a higher level.

2. Reduce friction and improve transmission efficiency

The use of high-performance lubricants and greases can reduce friction, improve transmission efficiency, reduce temperature rise and extend service life.

Improve the lubrication design of the ball track: By rationally designing the contact angle and contact method between the ball and the track and adopting an appropriate lubrication system, it is possible to reduce wear while ensuring efficiency.

3. Torsion resistance and stability

The bending and torsion resistance of ball screws can be improved by improving the size ratio of the screw or using high-strength materials.

4. Reduce gap and backlash control

Adjust the nut clearance: During the use of the ball screw, the clearance will cause distortion and vibration. By optimizing the nut structure and adjusting the gap between the nut and the ball, the backlash (i.e. reverse clearance) can be effectively reduced, thereby improving motion accuracy and response speed.
