6304 Ball Bearing
Size 20 x 52 x 15 mm. Single row deep groove ball bearing by AMB Bearings, Ahmedabad.
The 6304 is a single row deep groove ball bearing from the 6300 series (medium series, for heavier loads). It has a 20 mm bore, a 52 mm outside diameter and is 15 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 common in gearboxes, alternators, pumps, three-wheeler and car transmissions, and farm equipment. Because 6304 is a standard ISO number, the AMB 6304 fits wherever a 6304 from SKF, NBC, FAG, NTN or any other maker is specified.
