Multiple-varied designs and use of specialty steels today have allowed LEGEND to provide industry and commerce with the ability to increase loading capacities, reduce size and extend life expectancy beyond previously used slewing bearing designs. These bearing designs and their application must take into account a number of complex dynamic forces e.g.: axial/thrust load, high radial load, and moment load. Today¡¯s slewing bearings are used in some of the following industries and applications: construction industry, excavation industry, wind turbines, medical equipment, radar, military applications, port machinery, material handling machinery and oil industry to name but a few.
There are a number of basic designs that are best suited to individual applications, these can often be adapted by a mixture of categories to optimize performance, improve reliability and provide the most cost effective, efficient solution. The following are some categories available today: four and eight point contact ball, three row roller, bi-angular roller and taper designs. Drives are provided by inner or outer gear-drive, or driven directly by the inner or outer ring.
Dimension Range: from ID 250mm to OD 8000mm
Type: internal-geared, external-geared, non-gear
