This single row deep groove ball bearing has a bore diameter of 40.0 mm, an outside diameter of 90.0 mm, and a width of 23.0 mm. It belongs to Generation C design with a steel sheet metal cage (cage designation JN). The radial internal clearance is CN (Group N), which is the standard clearance range. The bearing has a net mass of 0.604 kg, a limiting speed of 11800.0 1/min, and a reference speed of 9900.0 1/min. The bore type is marked Z. The CN clearance class allows standard-fit mounting without additional preload considerations, and the steel sheet metal cage keeps the rolling elements guided under the stated speed range. Given the deep groove design, this bearing accommodates both radial loads and a degree of axial loading in both directions. A dimensionally and constructionally equivalent bearing is ZWZ 6308.
