SAK Bearing Co.,Ltd

Double row deep groove ball bearing is designed base on the single row deep groove ball bearings. The combination is  excellent adaptation of raceway groove and ball . 
Double row deep groove ball bearings can bear radial load, also can withstand axial load in both directions. Double row deep groove ball bearing has 4200 a, 4300 a types. A type bearing without ball gap. Two reinforced nylon cages can be inserted on both sides. Double row deep groove ball bearing can bear 1.62 times radial load than single row, it can also bear axial load. On base of same inner diameter, the double row deep groove ball bearing's width is larger, the load capacity is also higher than that of 6200 series and 6300 series (single row deep groove ball bearings)significantly.
