Features and advantages of SBK series ball screws

The SBK 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 SBK series ball screw is that the steel balls roll inside the screw threads and nuts, reducing friction, so the transmission efficiency is higher.

2. Low friction and long life

The SBK 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 SBK 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. Higher load capacity

Because the steel ball rolls between the screw and the nut, it can share a larger load. Compared with traditional linear bearings, the SBK series ball screw has a stronger load-bearing capacity. This makes it suitable for mechanical transmission applications requiring larger loads.

The performance improvement and solutions of ball Screw SBK 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 usage 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. Self-locking design

The ball screw adopts a self-locking design, which can automatically lock when there is no load or a small load, reducing the free movement of the system when it stops and improving the stability of the system.
