The 6328 M/C3 deep groove ball bearing features an inner diameter of 140 mm, an outer diameter of 300 mm, and a width of 62 mm, designed for high-speed and heavy-duty applications. It is constructed from standard bearing steel with a machined brass cage, providing durability and enhanced performance. The bearing has a slightly increased radial clearance (C3), allowing for thermal expansion and higher rotational speeds. Its open design facilitates direct lubrication and easy maintenance. Typical uses include large electric motors, industrial machinery, and power generation equipment, where reliability and precision are critical. The bearing supports radial loads with a basic dynamic load rating around 251 kN.
