4 point contact ball slewing bearings are necessary when in a given machine or system, one structural part needs to rotate in the opposite direction to another along a fixed axis, whilst guaranteeing the axial and radial link between the two parts.
The slewing bearing must support and transmit the operating loads of the structure to which it is connected; furthermore, slewing bearings must guarantee the application's required degree of precision, compliance with operating parameters and the requested life-cycle. It is clear that the slewing bearing is a fundamental component for the application in which it is inserted, which must be selected according to specific technical analyses. Technical staff at is at your service to provide assistance when selecting the most suitable slewing bearing for your application. The most common applications are: excavators, concrete pumps, boom lifts and man lifts, crane trucks, civil and harbour cranes, compactors, wind turbines, radars, manipulators and positioners, filling carousels, rotary tables.
