This single row deep groove ball bearing carries a 30.0 mm bore, 72.0 mm outside diameter and 19.0 mm width, with a net mass of 0.345 kg. It belongs to Generation C construction and is fitted with metal shields on both sides (2Z), combined with a stamped steel sheet metal cage (JN). The limiting speed is rated at 12800 1/min, with a reference speed of 11500 1/min. Radial internal clearance corresponds to C3 (Group 3), giving a larger internal clearance than the standard class, which compensates for tighter fits and temperature-related expansion during operation. The steel shields provide protection against dust ingress while allowing grease retention within the bearing, making this design suited for applications requiring a closed, low-maintenance rolling bearing with increased clearance for shaft and housing tolerances.
