This deep groove ball bearing carries radial and moderate axial loads through a single row of balls guided by a steel sheet metal cage. Bore diameter is 17.0 mm, outside diameter 47.0 mm, width 19.0 mm, and net mass 0.148 kg. The permissible limiting speed reaches 9700 1/min, and the bearing is fitted with C3 radial internal clearance, wider than normal. Sealing is provided on both sides (2RSR), keeping grease in and contaminants out, so no external protection or regreasing intervals are needed under normal conditions. The C3 clearance compensates for thermal expansion during operation, making the bearing suitable where operating temperatures rise above ambient. The steel sheet metal cage (JN) ensures stable ball guidance at the stated speed rating.
