This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a bore of 8.0 mm, an outside diameter of 16.0 mm, and a width of 5.0 mm. Net mass is 4.05 g, and the limiting speed reaches 26000 1/min. The bearing uses a steel sheet metal cage, designation JN, and features seals on both sides, symbol 2RSR. The radial internal clearance falls in the CN (Group N) range, suitable for standard fit conditions without special preload requirements. Seals on both sides keep grease inside and contaminants out, allowing the bearing to run without additional maintenance once mounted. The compact envelope and steel cage support the stated speed rating while keeping the design suitable for tight installation spaces.
