Description
The SKF 6304-2Z deep groove ball bearing combines robust performance with added protection from integral shields on both sides. These shields help retain lubricant and keep out contaminants, reducing maintenance demands and extending bearing service life. With a 20 mm bore, 52 mm outside diameter, and 15 mm width, it offers a compact yet strong solution for various industrial and mechanical applications.
Built from high-quality bearing steel and guided by a sheet metal cage, it delivers a dynamic load rating of 16.8 kN and a static load rating of 7.8 kN. Capable of running at speeds up to 15,000 r/min, this bearing ensures quiet, efficient operation with reliable load support in both radial and axial directions. Its CN internal clearance makes it suitable for standard fit applications, particularly in motors, gearboxes, and machinery where both durability and protection against contaminants are critical.
