Single row fully loaded cylindrical roller bearings are designed to withstand extremely heavy radial loads and medium speed applications. Due to the absence of a cage, the bearing can accommodate more rollers. NCF type bearings have integral retaining edges on both sides of the inner ring and retaining edges on one side of the outer ring, allowing for unidirectional axial displacement. The fixed ring on the outer ring can keep the bearing components integrated. The fixed ring cannot withstand axial loads during operation.
