This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, running with a bore diameter of 45.0 mm, an outside diameter of 85.0 mm, and a width of 23.0 mm. The net mass is 0.489 kg, and the limiting speed reaches 4650 1/min. The design integrates a steel sheet metal cage (JN) and seals on both sides (2RSR), keeping the internal grease fill protected from contamination while retaining lubricant within the bearing. Radial internal clearance corresponds to group CN, suitable for standard fit conditions without preload requirements. The sealed construction and cage design make this bearing suited for applications where relubrication access is limited and where consistent running behavior at the stated speed and clearance is required. The 62209-A-2RSR designation should be referenced when ordering to confirm correct sealing and cage variant.
