The 6301 deep groove ball bearing features a 12 mm bore diameter, 37 mm outside diameter, and 12 mm width, designed for high-speed and radial load applications. It offers a dynamic load rating around 10.1 to 12.1 kN and a static load rating near 4.2 kN, with a fatigue load limit of approximately 0.35 to 0.42 kN. The bearing supports speeds up to 20,000 rpm with grease lubrication and up to 24,000 rpm with oil. Variants include open, single or double shielded (metal or rubber seals), with cage materials typically pressed steel. It operates reliably between -40°C and 100°C, making it suitable for fans, pumps, and industrial machinery. Dimensions include a 1 mm minimum fillet radius.
