Company News1. Technical Background of Ball Screws
A ball screw is a high-precision transmission component that converts rotary motion into linear motion, or vice versa. Its core structure consists of a screw shaft, a nut, and rolling steel balls. Compared to conventional sliding screws, ball screws are widely utilized in CNC machine tools, industrial robots, precision instruments, automation equipment, and smart home systems (such as electric height-adjustable desks and motorized curtains) due to their low friction, high transmission efficiency, and superior accuracy.
In a ball screw system, the steel balls are critical for enabling low-friction rolling transmission, and their quality directly affects the positional accuracy, durability, and load-bearing capacity of the screw mechanism. YiHe steel balls, renowned for their high precision, low friction, exceptional wear resistance, and extended lifespan, play a crucial role in the optimal performance of ball screws. Based on customer applications and extensive research, we have summarized the key benefits and applications of steel balls in ball screws.
2. Role of YiHe Steel Balls in Ball Screw Systems
Enhancing Positioning Accuracy and Motion Stability
Ball screws are extensively used in precision machinery, semiconductor equipment, and high-end medical instruments, where ultra-high positioning accuracy is essential. YiHe steel balls, with their exceptionally smooth surface finish, help minimize vibration and positioning errors in ball screw operation, ensuring smooth and stable motion.
The high precision of YiHe steel balls also helps reduce backlash, thereby improving reversal accuracy and enhancing the stability of ball screws in high-precision transmission systems.
Reducing Noise and Ensuring Silent Operation
In precision transmission systems (such as smart home devices and medical equipment), low-noise operation is crucial. The ultra-fine processing technology of YiHe steel balls guarantees consistent surface smoothness and uniformity, reducing rolling noise and ensuring that ball screws maintain stable and silent operation even at high speeds.
By optimizing ball diameter and surface treatment, YiHe steel balls effectively reduce rolling contact vibration, further minimizing noise during operation.
