This is a single row deep groove ball bearing with a 100.0 mm bore, 180.0 mm outside diameter and 34.0 mm width, weighing 3.36 kg. It is fitted with shields on both sides and a steel sheet metal cage (JN), giving a limiting speed of 4250 1/min and a reference speed of 4800 1/min. Radial internal clearance corresponds to CN (Group N), the standard clearance class. The shielded design protects the raceway and balls from contamination while retaining the factory-applied grease, making relubrication unnecessary under normal operating conditions. With standard internal clearance and a steel cage, the bearing is suited for radial loads and light axial loads at the stated speed range, running true within the tolerances typical of standard accuracy. Dimensionally and constructionally equivalent to SKF 6220-2Z, NSK 6220ZZ and NTN 6220ZZ.
