This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore diameter of 30.0 mm, outside diameter of 90.0 mm, and width of 23.0 mm. The net mass is 0.722 kg. The bearing uses a steel sheet metal cage (JN) and runs with normal radial internal clearance (CN, Group N). Limiting speed is rated at 11000 1/min, with a reference speed of 9500 1/min. The normal internal clearance suits standard mounting conditions without additional preload requirements, while the steel sheet metal cage keeps the design suitable for the stated speed range. Bore type Z relates to the bore execution as specified by the manufacturer. Given its dimensions and speed ratings, this bearing fits applications requiring reliable radial support at moderate to high rotational speeds within the stated limits.
