This deep groove ball bearing carries radial and moderate axial loads through a single row of balls running in a groove-shaped raceway, with a steel sheet metal cage (JN) guiding the ball set. Bore diameter is 25.0 mm, outside diameter 47.0 mm, width 16.0 mm, net mass 0.102 kg, and the limiting speed is 8500 1/min. Radial internal clearance is CN (Group N), and the bearing is sealed on both sides (2RSR), corresponding to bore type Z. The two-side sealing keeps grease inside the bearing and blocks contaminants, so it runs pre-lubricated without needing external relubrication, provided the operating temperature stays within the limits of the grease used. Radial internal clearance in the CN group suits general applications without special fit requirements, and the steel cage gives stable ball guidance across the full speed range up to the stated limiting speed.
