The 6800 Series Thin Section Ball Bearings also known as the 61800 series are among the most popular choices for designers seeking a lightweight and high-speed bearing solution. Characterized by their thin cross-section these bearings allow for the use of larger shaft diameters and more robust housing designs within a smaller overall volume. This series is common in bicycle components electric motors and precision instruments where the combination of minimal friction high rotational speed and compact dimensions is essential for optimal equipment performance.
