This single row deep groove ball bearing carries the FAG designation 62303-A-2RSR, with a bore diameter of 17.0 mm, outside diameter of 47.0 mm, and width of 19.0 mm. Net mass is 0.148 kg, and the limiting speed reaches 9700 1/min. The bearing is fitted with a steel sheet metal cage (JN) and sealed on both sides (2RSR), giving protection against contamination and retaining internal lubrication. Radial internal clearance falls within group CN, the standard clearance range, suitable for general mounting conditions without special fit requirements. The double-sided sealing allows use where relubrication access is limited, while the steel sheet metal cage supports operation up to the stated limiting speed. The construction is intended for radial loads with the bearing running under normal thermal and speed conditions defined by the CN clearance group.
