Description
Deep groove ball bearing 6303-2Z-C3 from FAG carries a single row of balls in a steel sheet metal cage (JN design), fitted with steel shields on both sides. Bore diameter is 17.0 mm, outside diameter 47.0 mm, width 14.0 mm, net mass 113.1 g. Limiting speed reaches 18900 1/min, reference speed 15900 1/min, radial internal clearance is C3 (Group 3, above normal). The C3 clearance compensates for temperature rise and interference fits during mounting, keeping the bearing free of preload under operating conditions. Steel shields on both sides protect the raceway and balls from coarse contamination while retaining the internal grease fill, so no external relubrication path is provided. Equivalent bearings from other manufacturers matching this bore, outside diameter, width, shield configuration and clearance class are SKF 6303-2Z/C3, NSK 6303ZZC3, NTN 6303ZZC3.
