Deep groove ball bearing 61910-2RSR from FAG carries radial and moderate axial loads in a thin cross-section design, with a bore of 50.0 mm, outside diameter of 72.0 mm, and width of 12.0 mm. The bearing weighs 0.13 kg, has a limiting speed of 4700.0 1/min, and is fitted with a steel sheet metal cage (JN). Radial internal clearance is CN (Group N). Sealing on both sides (2RSR) protects the rolling elements from contamination and retains the internal lubrication charge, allowing operation without additional maintenance in installations where re-lubrication access is limited. The CN clearance corresponds to normal running fit, suitable for standard shaft and housing tolerances without preload or excessive play. Dimensionally and constructionally, this bearing corresponds to SKF 61910-2RS1, NSK 61910DDU, and NTN 61910LLU.
