This single row deep groove ball bearing carries a bore of 65.0 mm, outside diameter of 120.0 mm, and width of 23.0 mm, with a net mass of 0.977 kg. It uses a steel sheet metal cage (JN) and features a ceramic coating on the bore (Z). Radial internal clearance is C4, wider than standard, and the bearing supports a limiting speed of 8600 1/min with a reference speed of 6300 1/min. The ceramic coating on the bore provides electrical insulation, making this bearing suitable for applications where shaft currents need to be interrupted. The C4 clearance compensates for thermal expansion and interference fit effects during operation, allowing stable running under conditions that would otherwise tighten internal clearance. The steel sheet metal cage keeps rolling elements guided with low added mass, supporting the stated speed ratings. As an open bearing without seals or shields, relubrication access is direct, and lubricant selection should account for the operating speed range specified.
