The double-row deep groove ball bearing has an excellent tightness between the raceway and the steel ball, so the bearing can withstand the axial load acting in both directions in addition to the radial load. Double row deep groove ball bearings are suitable for bearing configurations where the load capacity of a single row deep groove ball bearing is insufficient. For double row deep groove ball bearings with the same outer diameter and inner diameter as deep groove ball bearings, the width is larger and the load capacity is much higher than that of the 6200 series and 6300 series single row deep groove ball bearings.
