This deep groove ball bearing carries seals on both sides and separates radial loads through a single row of balls guided by a steel sheet metal cage of design JN. Bore diameter is 10.0 mm, outside diameter 30.0 mm, and width 9.0 mm, with a net mass of 31.0 g. The limiting speed reaches 15400 1/min, and the radial internal clearance falls within group CN (Group N). The bore is executed in type Z, and the bearing is made from corrosion-resistant materials. The integrated seals on both sides retain lubricant inside the bearing and keep contaminants out, allowing operation without additional external sealing arrangements. The CN internal clearance suits standard running conditions without preload requirements, while the corrosion-resistant construction extends service life in environments where moisture or aggressive media would otherwise attack standard bearing steel. The compact bore and outside diameter combination, together with the rated limiting speed, make this bearing suitable for shaft arrangements requiring reliable rotation at the specified dimensions without relubrication access.
