This is a single-row deep groove ball bearing with a bore diameter of 50.0 mm, outside diameter of 110.0 mm, and width of 27.0 mm, weighing 1.077 kg. It is a Generation C design fitted with shields on both sides and a steel sheet metal cage (JN). The bearing carries a C3 radial internal clearance and reaches a limiting speed of 8000 1/min, with a reference speed of 8400 1/min. The shielded construction protects the raceway and balls from external contamination while retaining the internal grease fill, making relubrication unnecessary under normal operation. The C3 clearance compensates for temperature rise and interference fit during operation, keeping the bearing free of excessive preload. With its steel cage and single-row deep groove design, the bearing is suited for radial loads combined with moderate axial loads, running at speeds up to the stated limiting and reference values.
