This deep groove ball bearing supports radial loads and moderate axial loads in a single-row design with a bore of 40.0 mm, outside diameter of 68.0 mm, and width of 15.0 mm. It weighs 0.189 kg and is fitted with seals on both sides, combined with a steel sheet metal cage (JN). The limiting speed is rated at 5400.0 1/min, and the radial internal clearance corresponds to CN (Group N). The sealed design keeps the raceways protected from contamination and retains the internal lubricant, allowing operation without additional relubrication. The CN clearance is suited for standard mounting conditions without significant shaft or housing interference effects, and the steel cage provides stable ball guidance across the rated speed range. Dimensionally and constructionally equivalent to SKF 6008-2RS1, NSK 6008DDU, and NTN 6008LLU.
