Deep groove ball bearings such as the 6052, 6244, and 6338 models are precision-engineered for reliable performance in demanding electrical and industrial applications. These bearings feature robust cast iron sleeve construction, with bore sizes ranging from 260 mm to 190 mm, outer diameters up to 400 mm, and widths from 65 mm to 78 mm. They offer high dynamic load ratings up to 380 kN and static load ratings reaching 455 kN, ensuring durability under heavy loads. Designed for smooth operation, these bearings support high-speed rotation, provide excellent creep resistance, and are available with seals or shields for enhanced protection against contaminants.
