This deep groove ball bearing carries radial and moderate axial loads through a single row of balls running in a steel sheet metal cage (JN). Bore diameter is 45.0 mm, outside diameter 85.0 mm, width 19.0 mm, net mass 0.41 kg, and the limiting speed reaches 7100 1/min. It belongs to Generation C design and is fitted with seals on both sides (2HRS). The radial internal clearance is C3 (Group 3), which is wider than standard and compensates for thermal expansion under load or elevated operating temperature. The integrated seals retain grease inside the bearing and keep contaminants out, so no external sealing arrangement is required. This configuration suits applications where the shaft runs at higher speed and a slightly increased clearance is needed to maintain smooth operation without preload.
