Deep groove ball bearing 6217-2Z carries radial and axial loads in a single row of balls, with a bore of 85.0 mm, outside diameter of 150.0 mm, and width of 28.0 mm. It weighs 1.86 kg and is fitted with steel sheet metal shields on both sides, running in a steel sheet metal cage designated JN. Limiting speed is rated at 5700.0 1/min, with a reference speed of 5300.0 1/min, and the radial internal clearance falls in the CN (Group N) range. The shields on both sides protect the raceway and balls from dust and coarse contamination while retaining the internal grease fill, so the bearing is intended for grease lubrication rather than oil. Standard CN clearance combined with the JN cage suits general-purpose radial mounting positions where no special preload or increased clearance adjustment is required. Dimensionally and constructionally it corresponds to SKF 6217-2Z, NSK 6217ZZ, and NTN 6217ZZ.
