Carries radial loads and moderate axial loads in both directions as a single-row deep groove ball bearing of the 618 series, with a 130.0 mm bore, 165.0 mm outside diameter and 18.0 mm width. The rolling elements are guided by a steel sheet metal cage, designated JN. The bore is cylindrical, type Z, and the net mass is 0.794 kg. Reference speed is 3600.0 1/min and limiting speed 5500.0 1/min. Radial internal clearance is CN (Group N), the standard clearance for mounting with normal fits and ordinary operating temperatures. The thin section suits seats where axial and radial space is restricted, and the open design allows lubricant to be supplied from the surrounding arrangement. Dimensionally and structurally interchangeable with SKF 61826, NSK 61826 and NTN 61826.
