Deep groove ball bearing 16006-A-2Z carries radial and moderate axial loads on a shaft of 30.0 mm bore, with a 55.0 mm outside diameter and a narrow 9.0 mm width, giving it a low-profile design. The bearing has a single row of balls, shields on both sides, and a steel sheet metal cage (JN). Net mass is 85.0 g. The limiting speed reaches 15700.0 1/min, with a reference speed of 10000.0 1/min. The shields protect the raceway from dust and coarse contamination while retaining the internal grease fill, making relubrication unnecessary in typical operation. Radial internal clearance falls in the CN (Group N) range, suitable for standard fit conditions without preload. The narrow width and steel cage suit applications where axial space is limited and moderate speeds are required, with the stamped cage design keeping mass low relative to bearing size.
