Deep groove ball bearing 61956-MA-C3 carries radial loads through a single row of balls guided by a solid brass cage (MA). Bore diameter is 280.0 mm, outside diameter 380.0 mm, width 46.0 mm, and net mass 15.2 kg. Limiting speed reaches 2850.0 1/min, with a reference speed of 1990.0 1/min, indicating the thermal speed reference used for this bearing under standard conditions. The radial internal clearance is C3 (Group 3), providing greater internal play than a standard clearance class, which compensates for temperature-related expansion and slight shaft or housing fit interference during operation. The solid brass cage suits higher speed ranges and offers stable ball guidance under thermal load. As an open bearing without integrated sealing, it requires external protection against contamination and a separate relubrication scheme suited to the operating speed and load conditions.
