This is a single row deep groove ball bearing carrying radial and limited axial loads, with a bore diameter of 180.0 mm, outside diameter of 280.0 mm, and width of 31.0 mm. The bearing weighs 6.92 kg and features a steel sheet metal cage (JN). It is rated for a limiting speed of 3350.0 1/min and a reference speed of 2950.0 1/min, with radial internal clearance in class C3, which is wider than standard clearance. The C3 clearance compensates for thermal expansion during operation and interference fits, making this bearing suitable for applications where the shaft or housing fit reduces the internal clearance. The design allows radial loads with moderate axial components, and the wider clearance class supports stable running under elevated operating temperatures. Bore type Z refers to the specific bore tolerance execution.
