This deep groove ball bearing carries radial and moderate axial loads in a single row of balls running between a solid inner and outer ring. Bore diameter is 140.0 mm, outside diameter 210.0 mm, width 33.0 mm, and net mass is 3.56 kg. The bearing is fitted with metal shields on both sides (2Z) and runs on a steel sheet metal cage (JN). Limiting speed is 3600.0 1/min, reference speed 4050.0 1/min, and radial internal clearance corresponds to CN (Group N), the normal clearance group. The metal shields keep grease in place and reduce ingress of solid contaminants, so the bearing is suited for grease-lubricated positions without the need for external sealing, provided the shield type matches the working conditions. Normal internal clearance combined with the sheet metal cage supports operation at the stated speed range under standard alignment conditions. Dimensionally and constructionally, this bearing corresponds to SKF 6028-2Z, NSK 6028ZZ, and NTN 6028ZZ.
