This deep groove ball bearing carries radial and moderate axial loads on a single row of balls running between grooved inner and outer rings, with a 45.0 mm bore, 75.0 mm outside diameter and 16.0 mm width. It has seals on both sides and a steel sheet metal cage (JN), giving a net mass of 0.24 kg. Radial internal clearance is CN (Group N), and the limiting speed is rated at 4950 1/min. The integrated seals keep the factory-fill grease in place and block dirt and moisture ingress, so no external lubrication or maintenance is required during service. CN clearance suits standard fit conditions without added preload, and the steel cage supports stable ball guidance at the stated speed limit. Dimensionally and constructionally equivalent to SKF 6009-2RS1, NSK 6009DDU and NTN 6009LLU.
