The 6307ZZ bearing is a deep-groove ball bearing designed for radial loads, featuring an inner diameter of 35 mm, an outer diameter of 80 mm, and a width of 21 mm. It is constructed from high carbon chrome steel with a pressed steel cage, offering a basic dynamic load rating of approximately 33.5 kN to 41.7 kN depending on the manufacturer. This bearing is shielded, providing protection against contaminants, and is suitable for applications requiring high rotational speeds up to 8500 rpm. The radial clearance is typically set to C3 for optimal performance in various environments.
