Triple-row roller slewing bearings are an excellent choice for heavily loaded applications. These bearings are combined cylindrical roller radial/thrust bearings, consisting of one one-piece and one two-piece ring as well as two roller sets to accommodate axial loads, and one roller set to accommodate radial loads. Polyamide cages separate the axially loaded rolleres. The bearings are not preloaded and have integral lip seals. They provide the highest load ratings possible and can accommodate much heavy loads and high tilting moments.
These bearings can be manafactured as with an external gear, with an internal gear, ungeared.
Applications: mainly used for offshore applications, bucket wheel excavators, cranes of all types, and so on.
