Precision ball linear slide CNC machine tool
Designed specifically for CNC machining centers, CNC lathes, five-axis machine tools, and engraving and milling machines, this is a core load-bearing component for achieving high-precision linear motion.
Utilizing a four-row circular arc contact ball bearing design, it can simultaneously withstand loads in four directions (up, down, left, and right), increasing dynamic rigidity by 35% and easily handling demanding conditions such as heavy cutting and high-speed milling. Precision grades range from H to P, with a travel parallelism ≤0.006mm/1000mm and a repeatability of ±0.001mm, ensuring long-term consistency in the micron-level machining accuracy of molds and precision parts.
An optimized ball recirculation system with a DN value of 120,000 ensures smooth, jam-free operation and noise levels below 52dB. Constructed from high-carbon chromium bearing steel with integral quenching, achieving a hardness of HRC60-62, and featuring multiple contact dustproof seals, it effectively blocks metal shavings and oil contaminants, extending service life by more than 2 times. All parts are inspected before shipment, and customized preload levels, special coatings, and non-standard lengths are supported.
