The NNCF48 type is a double row fully loaded cylindrical roller bearing (without a cage) with a three speed inner ring and a single speed outer ring. It has extremely strong radial bearing capacity and is suitable for heavy-duty medium and low-speed working conditions. It is commonly used in equipment such as rolling mills, gearboxes, and machine tools.
