This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a bore of 10.0 mm, outside diameter of 26.0 mm and width of 8.0 mm. The bearing belongs to Generation C design and weighs 0.018 kg, with a limiting speed of 28500 1/min. It is fitted with seals on both sides (2HRS) and uses a steel sheet metal cage (JN), with radial internal clearance C3, providing a larger internal clearance than standard. The C3 clearance compensates for thermal expansion and interference fit effects, allowing stable operation under conditions where the shaft or housing fit would otherwise reduce running clearance. The seals on both sides retain the internal lubricant and protect against dust and moisture ingress, so the bearing runs sealed-for-life without need for relubrication. The steel sheet metal cage guides the balls with low friction, suiting the bearing to compact applications where the given bore-to-width ratio and limiting speed define the operating range.
