A single row deep groove ball bearing with bore 40.0 mm, outside diameter 80.0 mm and width 18.0 mm, mass 378.18 g. Both sides are fitted with metal shields, and the cage is a steel sheet metal type (JN). Radial internal clearance corresponds to C2 (Group 2), which is tighter than the standard clearance range. Limiting speed is 10400 1/min, reference speed 9300 1/min. The reduced C2 clearance suits applications where shaft and housing fits would otherwise increase running clearance beyond the normal range, keeping radial play controlled. Metal shields restrict grease loss and limit ingress of coarse contaminants without contact seal drag, and the bearing is intended for grease lubrication.
