The 6328 M/C3 deep groove ball bearing features a 140 mm inner diameter, 300 mm outer diameter, and 62 mm width, designed for heavy-duty industrial applications. It has an open design with a brass cage and slightly increased radial clearance (C3), allowing for high-speed operation and moderate temperature tolerance. Manufactured from standard bearing steel, it offers a basic dynamic load rating around 251 kN and a static load rating near 246 kN. The bearing’s cylindrical bore and open configuration facilitate easy lubrication and maintenance, making it suitable for large electric motors, pumps, compressors, and construction machinery. An oversized cast iron sleeve with an approximate outer diameter of 309 mm and length of 120 mm is commonly paired with this bearing for precise fitting.
