Precision ball screws are essential machine components. They convert rotary motion into linear motion with high efficiency. It consists of a screw shaft, a nut and ball bearings, between which the balls roll, thus reducing friction. These screws offer high accuracy and repeatability, which is essential for applications that require precise positioning. They are highly efficient and have low power consumption. Low friction ensures smooth operation. Their high load capacity is ideal for heavy-duty tasks. Widely used in CNC machine tools, robots and medical equipment, precision ball screws play a key role in modern manufacturing and precision engineering.

How to ensure the accuracy level of ball screw?
Through precise processing technology, such as high-precision grinding and lapping processes, and strict quality inspection processes, including dimensional accuracy, form and position tolerance and other aspects of inspection, ensure that the ball screw reaches the corresponding accuracy level.
What are the differences in the service life of ball screws of different materials?
Alloy steel has high strength and good wear resistance, is suitable for heavy loads and conventional working conditions, and has a long service life; stainless steel 304, 316 and other materials have strong corrosion resistance, can maintain good performance in environments with corrosion risks, and the service life is less affected by corrosion factors.
In what specific aspects does surface treatment improve the performance of ball screws?
For example, hard chrome plating can improve surface hardness, wear resistance and corrosion resistance, and reduce friction coefficient; nitriding can form a wear-resistant and corrosion-resistant nitrided layer to improve fatigue strength. These treatments can reduce wear, extend service life, and stabilize performance under different working conditions.
