In contrast to normal cylindrical roller bearings, full complement cylindrical roller bearings do not contain a cage, thereby facilitating a maximum of cylindrical rollers in the available cross-section. They are therefore especially suited for bearing positions where particularly heavy loads are involved.This type of bearing involves high friction forces due to the physical contact between the cylinder rollers and have, therefore, lower ceiling speeds than their counterparts with a cage.STC-Steyr manufactures single-row, full complement cylindrical roller bearings in NCF and NJG construction types.Double-row, full complement cylindrical roller bearings are produced in the following construction types: NNC, NNCF, NNCL and NNF.
