The NNCF49 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 with a fixed ring. It has strong radial bearing capacity and rigidity, 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 tool spindles.
