This deep groove ball bearing carries radial loads through a single row of balls guided by a steel sheet metal cage (JN). Built to Generation C design with an integrated seal on both sides, it has a bore diameter of 20.0 mm, outside diameter of 52.0 mm, and width of 15.0 mm. Net mass is 0.145 kg, limiting speed reaches 14000 1/min, and radial internal clearance corresponds to class CN (Group N). The integrated seal keeps grease inside the bearing and blocks contamination from the raceway, supporting continuous operation without frequent relubrication. The CN clearance suits standard shaft and housing fits, while the steel cage maintains stable ball spacing up to the stated limiting speed. Bore type Z relates to the bore geometry on the inner ring side.
