Carries radial loads at small shaft diameters, running on a single row of balls with two rubber seals fitted on both sides to keep the raceway protected. Bore diameter is 6.0 mm, outside diameter 17.0 mm, width 6.0 mm, net mass 0.006 kg. The cage is a sheet steel design (JN), radial internal clearance is CN (Group N), and the limiting speed reaches 29500 1/min. The sealed construction (2RSR) keeps grease inside and contaminants out, so the bearing arrives pre-lubricated and does not require additional relubrication under normal conditions. CN clearance corresponds to standard internal clearance, suitable for standard shaft and housing fits without special preload or thermal expansion compensation requirements. The steel sheet metal cage guides the balls at the rated speed while keeping the overall mass low, matching the compact envelope of this deep groove ball bearing.
