NFZ Internal Cycle Fixed Preload Ball Screw with Increased Ball Diameter |
The NF Internal Circulation Fixed Ball Screw represents a key technical upgrade and iterative development of conventional slide ball screw products. Structurally assembled with precision screw bodies, fixed nuts and circulating steel balls, its core function is to convert rotary motion to linear motion and reverse, providing accurate and efficient motion transmission for mechanical systems. The technological innovation of this product is comparable to the revolutionary upgrade of bearings from sliding friction to rolling friction, which fundamentally optimizes the friction transmission mode of traditional mechanical structures. Thanks to its excellent low-friction mechanical properties, the NF internal circulation fixed ball screw effectively reduces operational resistance and energy consumption, achieving smoother transmission, higher efficiency and better operational stability compared with ordinary slide ball screws.
With outstanding low-friction performance, reliable positioning accuracy and stable long-term operation, the NF Internal Circulation Fixed Ball Screw adapts to various precision and general industrial working conditions. It is widely used in all types of standard industrial automation equipment, precision testing instruments, small and medium-sized CNC supporting equipment and conventional mechanical transmission systems. Its fixed internal circulation structure ensures compact installation, stable operation and low noise, perfectly meeting the daily operation and precision transmission needs of mainstream industrial manufacturing and precision instrumentation fields.
Our enterprise boasts profound industry accumulation and leading R&D strength in the ball screw manufacturing industry. Since independently developing China’s first domestic ball screw in 1964, we have maintained a leading position in domestic ball screw research, development and production. Centering on the upgrading needs of modern CNC machine tools and industrial equipment, we have established a clear product development direction focusing on large size, heavy load, high speed and high precision. The NF Internal Circulation Fixed Ball Screw, as one of our mature core products, coordinates with our independently developed DKFZD end-cap high-speed precision ball screw and JF/JFZD heavy-load ball screw series. All innovative products are equipped with independent intellectual property rights, with a total of 14 patented technologies obtained through independent research and development, technical declaration and licensing, realizing independent control of core product technologies.
In terms of production and processing technology, we take the lead in applying professional induction hardening technology for ball screw heat treatment, which greatly improves product surface hardness, wear resistance and overall production efficiency. In recent years, we have completely reformed the decades-old traditional processing techniques by introducing world-class German high-speed hard whirling processing technology. The advanced international technology comprehensively improves product processing accuracy, finished product quality and production efficiency. Combined with our customized fixed-length pre-processing production mode, we effectively shorten the product production cycle, with the shortest lead time compressed to 15 days, providing efficient and flexible delivery services for global customers.
We possess super strong comprehensive production capacity and full-spec product coverage for the NF Internal Circulation Fixed Ball Screw. Our production range covers a minimum diameter of 6mm and a minimum lead of 1mm, a maximum diameter of 245mm and a maximum single processing length of 10 meters, with a maximum load capacity exceeding 125 tons. We can stably mass supply ball screws of multiple international precision grades, including 1.5m P0, 2m P1, 4m P2, 5m P3 and 10m P5 grades. As a professional full-spec ball screw manufacturer, we can support standardized mass production and customized processing of the NF series products, providing high-cost-performance and reliable precision transmission components for various industrial scenarios.
