The 6700 Series Ultra Thin Section Ball Bearings represent the most space-efficient design in the deep groove family offering an extremely small cross-section relative to their bore diameter. These ultra-lightweight bearings are specifically engineered for applications where radial space is at an absolute premium and overall weight reduction is critical such as in drones optical devices and miniature robotics. Despite their extremely thin profile they are manufactured to high precision standards to ensure consistent rotational performance and are ideal for providing stable movement in highly congested mechanical assemblies.
