71800 Series Super Precision Angular Contact Ball Bearings

The 718 Series is characterized by an extremely light and thin cross-section, offering a unique solution for high-precision applications where space is at a premium. Despite their compact dimensions, these super precision angular contact ball bearings maintain exceptional rigidity and rotational accuracy. They allow for larger shaft diameters to be used within the same housing space, significantly enhancing the stiffness of the overall assembly. This makes them the industry standard for robotic arm joints, high-precision measuring instruments, rotary tables, and semiconductor manufacturing equipment where every millimeter counts.
