Double row deep groove ball

Double row deep groove ball bearings have a double row rolling element structure, which has a much better radial bearing capacity than single row models. The structure is compact and adaptable, and can withstand slight axial loads in both directions. It operates stably and has good rigidity, and is suitable for various rotating transmission conditions of medium and heavy loads. It is widely used in metallurgical machinery, mining equipment, heavy machinery and other fields.
