This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, running on a bore of 20.0 mm, outside diameter of 42.0 mm and width of 12.0 mm. It belongs to Generation C design (6004-C-2HRS-L038>V), fitted with seals on both sides and a steel sheet metal cage (JN). Net mass is 0.065 kg, and the limiting speed reaches 15300.0 1/min. Radial internal clearance falls in CN (Group N), suitable for standard fit conditions without preload requirements. The sealed construction retains grease inside and keeps contaminants out, so relubrication is not required during service. With a steel sheet metal cage and normal clearance, the bearing suits applications requiring reliable rotation at the given speed limit without special alignment demands.
