Four-row cylindrical roller bearings are mainly used in rolling mill machinery such as cold and hot rolling mills and blanking machines. The bearings are separated structures, and the bearing rings and rolling element assemblies can be easily separated. Therefore, the bearings are cleaned, inspected or It is very convenient to install and disassemble.
FC type: The FC type bearing is composed of two outer rings and one inner ring, and each of the outer rings has a middle rib in the middle of the rib and a rib in the inner ring.
FCD type:The FCD type bearing is actually a combination of two NN type bearings.
FC and FCD bearings allow for axial displacement in the axial direction relative to the housing. Therefore, such a structure is suitable as a swim end bearing. Car cages are often used for cages of this type.
