Full complement cylindrical roller bearings have no cage and full of rollers, they can therefore carry very heavy radial loads. But, the high speed performance is worse compared with bearings with cage. Full complement cylindrical roller bearings include single row Full complement cylindrical roller bearings( type NCF) and double row Full complement cylindrical roller bearings (type NNCF). Type NCF ---- Full complement cylindrical roller bearings of NCF designs can carry axial loads in one direction and provide axial load location in one direction. Type NNCF --- Full complement cylindrical roller bearings of NNCF designs can carry axial loads in one direction and provide axial load location in one direction. --- can carry very heavily load with slow speed. Single and double rows open bearings are primarily used in general mechanical equipment required lower speed and heavy loads. Doule row closed bearings are generally used in wire rope pulleys of cranes. They are mainly used in machine tools, rolling mill stands, plastic calenders, grinding mills and also large gearboxes.
