6203 Ball Bearing
Size 17 x 40 x 12 mm. Single row deep groove ball bearing by AMB Bearings, Ahmedabad.
The 6203 is a single row deep groove ball bearing from the 6200 series (light series, the most common size range). It has a 17 mm bore, a 40 mm outside diameter and is 12 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 6203 is a standard ISO number, the AMB 6203 fits wherever a 6203 from SKF, NBC, FAG, NTN or any other maker is specified.
