Carries radial and light axial loads through a single row of balls running in a deep groove raceway, giving the design its self-retaining, low-friction character. Bore diameter is 40.0 mm, outside diameter 68.0 mm, width 15.0 mm, and net mass is 0.189 kg. The bearing is fitted with metal shields on both sides and uses a pressed steel sheet cage (JN). Limiting speed is rated at 12400 1/min, with a reference speed of 10600 1/min. Radial internal clearance is CN (Group N), suitable for standard fits without preload adjustment. The steel shields protect the raceway from coarse contamination while allowing the factory grease fill to remain in place, so no external sealing or relubrication is required in normal operation. Dimensionally and constructionally equivalent to SKF 6008-2Z, NSK 6008ZZ, and NTN 6008ZZ.
