This deep groove ball bearing carries radial and moderate axial loads through a double row of balls, giving higher load capacity within the same envelope as a single-row design. Bore diameter is 55.0 mm, outside diameter 120.0 mm, width 43.0 mm, and net mass 2.06 kg. The bearing runs with a plastic cage (TVH), permitting a limiting speed of 5100 1/min and a reference speed of 4650 1/min. Radial internal clearance is CN (Group N), the standard clearance suited to normal operating conditions without special preload or looseness requirements. The double-row arrangement gives the bearing greater rigidity and load-carrying capacity than a single-row bearing of comparable size, while the plastic cage reduces friction and mass compared with a pressed steel cage, supporting stable ball guidance at the stated speeds. As the bearing is open, external sealing and a separate lubrication supply must be provided by the housing design.
