The 6206 is a high-precision open-type ball bearing engineered for advanced mechanical assemblies that utilize oil-bath or oil-mist lubrication systems. By removing integrated seals and shields, this unshielded configuration achieves the absolute minimum rotational resistance and zero contact friction. With its standard 30mm bore and 62mm outer diameter, the 6206 Open Type is a critical component for high-speed gearboxes, internal combustion engine components, and specialized industrial spindles where thermal efficiency is a priority.
