Deep groove ball bearing supports radial loads and moderate axial loads through a single row of balls guided by a steel sheet metal cage (JN). Bore diameter is 40.0 mm, outside diameter 68.0 mm, width 15.0 mm, and net mass 0.181 kg. Limiting speed reaches 14600 1/min, with a reference speed of 10600 1/min. Radial internal clearance is C3 (Group 3), providing greater internal play than standard clearance to compensate for thermal expansion during operation. The C3 clearance makes this bearing suitable for applications where operating temperatures raise the shaft-to-housing temperature differential, preventing excessive preload. The steel sheet metal cage keeps mass low and allows stable ball guidance at the stated speed ratings. Dimensionally and constructionally, it corresponds to SKF 6008/C3, NSK 6008C3, and NTN 6008C3.
