Slewing Bearings




Design of the support structure the slewing ring has a limited axial stiffness: the diameter is large compared to the cross section. It must be mounted on a machined supporting base, ensuring sufficient stiffness with regard to the loads to be transferred. This makes it possible to ensure an even distribution of stresses and to avoid any deformation during operation, which would be harmful to the good working of the bearing. Therefore, it is necessary to use supporting bases with a minimum thickness not less than the values indicated in the table above. The width of the supporting surfaces is to be at the least equal to that of the ring.
