This deep groove ball bearing carries a single row of balls in a thin-section design, with a bore of 17.0 mm, outside diameter of 26.0 mm and width of only 5.0 mm, giving a net mass of 0.006 kg. Both sides are fitted with metal shields, and the ball complement runs in a steel sheet metal cage (JN). The limiting speed reaches 35000 1/min, with a reference speed of 17100 1/min, and radial internal clearance is standard CN (Group N). The narrow cross-section and low mass make this bearing suited for compact housings where axial space is restricted rather than load capacity being the priority. The metal shields on both sides keep out coarse contaminants while retaining the factory-applied grease, so no additional sealing is required in service. With standard CN clearance and a steel cage, the bearing runs predictably at moderate speeds without need for special mounting tolerances.
