Deep Groove Ball Bearing – 6304-2Z/C3

The SKF 6304-2Z/C3 deep groove ball bearing is designed for reliable performance in demanding applications where both durability and efficiency are critical. Featuring shields on both sides, the bearing retains lubricant and prevents the ingress of dust and contaminants, extending service life with minimal maintenance. The C3 internal clearance offers greater tolerance for heat-induced expansion, making this bearing particularly suitable for high-speed or high-temperature environments. With a 20 mm bore, 52 mm outside diameter, and 15 mm width, it delivers a compact yet robust solution capable of handling radial and axial loads in both directions. Constructed from premium bearing steel and equipped with a sheet metal cage, it provides a basic dynamic load rating of 16.8 kN and a static load rating of 7.8 kN. The bearing achieves reference speeds up to 30,000 r/min and limiting speeds of 15,000 r/min, ensuring smooth, low-noise operation across various industrial applications, including electric motors, gearboxes, and mechanical systems requiring both speed and resilience.
