This deep groove ball bearing carries radial loads through a single row of balls guided by a solid brass cage (MA), with a holding groove design and bore type Z. Bore diameter is 480.0 mm, outside diameter 650.0 mm, width 78.0 mm, and net mass 75.0 kg. The limiting speed is 1630.0 1/min, with a reference speed of 1130.0 1/min. Internal clearance is set to C3 (Group 3), providing increased radial play to compensate for tight fits and thermal expansion during operation at higher loads. The solid brass cage supports stable ball guidance at the given speed range, while the holding groove design assists in axial positioning of the bearing. This configuration is suited for applications requiring reliable radial load support at larger shaft diameters, where the specified clearance and cage design maintain smooth rotation under the stated speed limits.
