This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore of 30.0 mm, outside diameter of 55.0 mm and width of 13.0 mm. It has metal shields on both sides, a steel sheet metal cage (JN), and C3 radial internal clearance, giving a net mass of 0.116 kg. The limiting speed is 15700 1/min, with a reference speed of 13100 1/min. The C3 clearance compensates for temperature rise and interference fits, keeping the bearing free from excessive preload during operation. Metal shields protect the raceway from coarse contamination while allowing grease relubrication is not intended, as the bearing is grease-filled for its service life. This design suits applications requiring stable radial guidance at moderate to high speeds. Equivalent references: SKF 6006-2Z/C3, NSK 6006ZZC3, NTN 6006ZZC3.
