This deep groove ball bearing carries radial and moderate axial loads in a single row of balls running between a bore of 120.0 mm and an outside diameter of 180.0 mm, with a width of 19.0 mm and a net mass of 1.567 kg. The steel sheet metal cage (JN) guides the balls, and the design allows a limiting speed of 5200.0 1/min and a reference speed of 3550.0 1/min. Radial internal clearance is set to CN (Group N). The standard clearance class supports smooth running under typical radial loading, while the narrow cross-section relative to the bore keeps the bearing compact for its load capacity. The steel cage construction gives it stable ball guidance at the stated speed ratings, and the open design (bore type Z) requires external sealing and a separate lubrication supply to protect the raceways and rolling elements during operation.
