This deep groove ball bearing carries radial and moderate axial loads in a single row of balls running in deep raceway grooves. Bore diameter is 40.0 mm, outside diameter 80.0 mm, width 18.0 mm, and net mass is 0.336 kg. The cage is a steel sheet metal design (JN), and the bearing belongs to Generation C construction. Limiting speed is rated at 13600 1/min, with a reference speed of 10500 1/min. Radial internal clearance falls in the CN (Group N) range, suitable for standard fit and operating conditions without special preload requirements. The steel sheet metal cage keeps mass low and supports stable ball guidance at higher speeds within the stated limits. With standard clearance and a normal-tolerance bore, this bearing fits general shaft arrangements where straightforward mounting and predictable running clearance are required.
