This single row deep groove ball bearing carries a bore diameter of 85.0 mm, an outside diameter of 130.0 mm and a width of 22.0 mm, with a net mass of 0.94 kg. It is fitted with shields on both sides (2Z) and a steel sheet metal cage (JN), running with normal radial internal clearance (CN, Group N). The limiting speed is rated at 6100 1/min, with a reference speed of 5800 1/min. The steel shields protect the raceway and balls from dust and coarse contaminants while retaining the initial grease fill, so the bearing is suited for grease lubrication without additional sealing arrangements. Normal internal clearance keeps radial play within standard limits, supporting radial loads and moderate axial loads under typical shaft and housing fits. Dimensionally and constructionally this bearing corresponds to SKF 6017-2Z, NSK 6017ZZ and NTN 6017ZZ.
