High Quality Single Row Ball Slewing Bearing with Raceways Heat Treatment
Slewing bearing as a component of the mechanical equipment,it has a certain service life. The raceway heat treatment is very import for the service life and loading capacity.
External gear single row ball four-point contact slewing bearing 011 series.
The single-row four-point contact ball slewing ring is composed of two seat rings and has a compact structure. The steel ball contacts the arc raceway at four points. The size of the single-row ball slewing ring is large, mainly 0.4 to 10 meters, and some up to 40 meters, which can withstand several aspects of pressure. In addition, the single-row ball slewing bearing has a low operating speed and can achieve continuous rotation. The single-row ball slewing bearing has a relatively strong bearing capacity, can bear axial force, radial force and tilting moment, and can realize continuous rotation, especially reciprocating rotation within a certain angle, which is equivalent to the so-called "swing bearing".
Mainly used for truck cranes, tower cranes, excavators, pile drivers, graders, road rollers, dynamic compactors, rock drilling machinery, engineering vehicles, radar scanning equipment, etc. to bear the overturning moment, vertical axial force, and horizontal inclination force.
