6303 Ball Bearing
Size 17 x 47 x 14 mm. Single row deep groove ball bearing by AMB Bearings, Ahmedabad.
The 6303 is a single row deep groove ball bearing from the 6300 series (medium series, for heavier loads). It has a 17 mm bore, a 47 mm outside diameter and is 14 mm wide. It carries radial load with some axial load in both directions and runs smoothly at high speed.
Sizes in this bore range are widely used in two-wheeler wheels, small electric motors, fans, pumps and light machinery. Because 6303 is a standard ISO number, the AMB 6303 fits wherever a 6303 from SKF, NBC, FAG, NTN or any other maker is specified.
