The NAG type is a double row fully loaded cylindrical roller bearing (without a cage), non separable, with a three speed inner ring and a single speed outer ring. It has strong radial and bi-directional axial bearing capacity and is suitable for heavy-duty medium and low-speed working conditions. It is commonly used in equipment such as pulleys, construction machinery, and industrial machinery.
