This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, running with a bore of 50.0 mm, an outside diameter of 80.0 mm, and a width of 10.0 mm at a net mass of 0.175 kg. The steel sheet metal cage (JN) keeps ball spacing stable at higher speeds, supporting a limiting speed of 12200 1/min and a reference speed of 6300 1/min. Radial internal clearance falls in the CN (Group N) range, giving standard running clearance suited to typical fits and moderate temperature rise. The narrow 10.0 mm width keeps the axial footprint compact, and the design allows mounting in applications requiring reliable rotation at the stated speed range with standard bore tolerance.
