The Cold-Rolled Ball Screw is a high-efficiency transmission component precision-machined via cold rolling process. It realizes the efficient conversion between rotary motion and linear motion by replacing sliding friction with rolling friction of balls between the screw and nut. With outstanding advantages such as high precision, high rigidity, long service life and low energy consumption, the cold rolling process endows it with excellent surface quality and dimensional consistency. It is widely used in CNC machine tools, automated production lines, precision conveying equipment and other industrial fields that require high transmission efficiency and positioning accuracy.
Product Advantages
Widely used in industrial fields with high requirements for transmission efficiency and positioning accuracy, such as precision conveying equipment
High-efficiency transmission, energy saving and consumption reduction
High-efficiency transmission, energy saving and consumption reduction: The ball rolling friction structure enables transmission efficiency of over 90%, which is more than 40% more energy-efficient than traditional trapezoidal screws, significantly reducing equipment operating energy consumption.
Precision positioning, stable operation
The cold rolling process ensures that the screw pitch accuracy error is ≤0.015mm/300mm. Combined with the preloaded nut design, it effectively eliminates axial clearance, and the positioning accuracy can reach ±0.005mm.
High strength and rigidity
Made of SCM440 alloy structural steel, strengthened by integral heat treatment, the radial rigidity of the screw is increased by 25%, which can bear large radial and axial loads, suitable for heavy-load working conditions.
Long-lasting durability, easy maintenance
The sealing structure effectively blocks the intrusion of dust and impurities. Combined with the lifelong lubrication design, the service life can reach more than 10,000 hours under normal working conditions, and the maintenance cycle is extended to 6-12 months.
