This deep groove ball bearing carries radial and moderate axial loads in a single row configuration, with a bore diameter of 120.0 mm, outside diameter of 260.0 mm, and width of 55.0 mm. The bearing weighs 14.78 kg and features a solid brass cage (M), allowing a limiting speed of 4550.0 1/min and a reference speed of 3800.0 1/min. The C3 radial internal clearance provides increased internal play, compensating for thermal expansion during operation and interference fit mounting. The solid brass cage offers stable ball guidance and mechanical strength at the rated speeds. This design suits applications requiring reliable operation under combined loading with standard lubrication, without integrated sealing, so external contamination protection and lubricant supply must be provided by the housing arrangement.
