This single row deep groove ball bearing carries the bore code 6315-M-J20GA-C3, with a 75.0 mm bore diameter, 160.0 mm outside diameter, and 37.0 mm width. It weighs 3.67 kg net and runs with a solid brass cage (M) carrying a ceramic coating (J20GA), designed with C3 radial internal clearance for increased operating looseness. The limiting speed reaches 8200 1/min, with a reference speed of 5800 1/min. The C3 clearance compensates for thermal expansion and interference fit growth during operation, allowing the bearing to run without excessive preload under elevated temperatures. The solid brass cage provides guidance stability at higher speeds and reduces wear compared to lighter cage designs, while the ceramic coating on the cage improves electrical insulation properties, reducing the risk of current passage through the rolling elements. No sealing or integrated lubrication is included, so relubrication intervals depend on the application's operating conditions and mounting arrangement.
