The 6021 is a high-precision, unshielded radial ball bearing designed for seamless integration into sophisticated mechanical systems. Part of the 6000 "Extra Light" series, it provides a large 105 mm bore within a space-efficient 160 mm outer diameter, making it the perfect solution for heavy-duty shafts requiring high rotational accuracy. This open-type configuration is specifically intended for environments where external oil-mist or oil-bath lubrication is continuously supplied, ensuring maximum service life in high-speed industrial gearboxes.
