With a 100 mm bore and a slim 13 mm cross-section, this open configuration eliminates the friction and speed limitations of shields or seals, allowing for higher operating speeds and direct access for oil lubrication. The 6820 Open is a thin-section deep groove ball bearing designed for applications requiring maximum rotational speed, custom lubrication strategies, or integration into assemblies with external sealing provisions. It is the preferred choice for precision spindles, high-speed machinery, and systems where the housing itself provides contamination protection.
