Carries radial loads and some axial load in both directions on a single row of balls, in the H-Series design with shields on both sides and a steel sheet metal cage of type JN. Bore diameter is 20.0 mm, outside diameter 42.0 mm and width 12.0 mm, with a net mass of 0.071 kg. Bore type is Z. Reference speed is 18200 1/min and limiting speed 21100 1/min. Radial internal clearance is C3, a clearance greater than normal, which leaves more room after the fit and thermal expansion have reduced it in the mounted state. The shields retain the grease filling and keep the bearing closed without contact with the inner ring, so no relubrication is foreseen. Both speed figures are read for separate operating conditions and should not be exceeded.
