Deep groove ball bearing carries radial and moderate axial loads through a single row of balls guided by a steel sheet metal cage (JN). The bore is 40.0 mm, outside diameter 68.0 mm, width 15.0 mm, and net mass is 0.188 kg. Sealing on both sides (RSR design) keeps contamination out and retains lubricant inside the bearing. Limiting speed is rated at 5400.0 1/min, and radial internal clearance corresponds to CN (Group N), the normal clearance group. The seals and normal clearance class make this bearing suited for applications with standard alignment requirements and no special provision for external relubrication, since the integrated seals restrict access to the raceway. Normal internal clearance keeps operation within typical tolerances for shaft and housing fits without additional preload considerations. Dimensionally and constructionally equivalent to SKF 6008-RS1, NSK 6008DU, and NTN 6008LU.
