Without gear four-point contact rolling element ball bearings
Four-point contact rolling element ball bearings is mainly made up of inside and outside rings.Ball slewing bearing has the features of compact in design, and light in weight. The balls roll on the circular race at four points, so it can undertake the axial force, radial force and tipping moment at the same time.This series of four point contact ball bearings are suitable in many engineering machinery, such as rotary conveyor welding operation machine, small cranes, small and medium-sized excavators and so on.We offer our products in accordance with the client's requirements, no teeth type (non-geared), outer teeth type (external geared), inner teeth type (internal geared) are all available.
Four point contact rolling element ball bearings application in cranes is one of important load supporting parts on a crane. It is connected with slewing table weldment of complex structure and loads. With finite element method as a tool, a model of finite element calculation is set up for Four point slewing ring of truck crane and structural strength and rigidity analysis are conducted on it.
