Carries radial loads and moderate axial loads through a single row of balls guided by a steel sheet metal cage (JN). The 6211-Z-N deep groove ball bearing has a bore of 55.0 mm, outside diameter of 100.0 mm and width of 21.0 mm, with a net mass of 0.62 kg. It is fitted with a shield on one side and features a ring groove on the outer ring for retaining ring fitment. Limiting speed is 9500 1/min, reference speed 7500 1/min. Radial internal clearance falls in the CN (Group N) range, suiting standard fit conditions without added preload requirements. The steel sheet metal cage keeps mass low and allows stable ball guidance at the stated speed range, while the single-side shield restricts contamination ingress from that side, leaving the open side accessible for relubrication with grease or oil as required by the mounting arrangement. The ring groove permits axial location using a retaining ring where the housing design calls for it.
