Light type external gear slewing bearing

Light external gear slewing bearing consists of two rings (one inner ring and one outer ring.) It has compact structure and light weight. As its balls are four point contacted with the raceway, the slewing bearing can take axial load, radial road, and tilting moment at the same time. 

The light external gear slewing bearing slewing bearing has the same structure with the ordinary slewing,but the weight is light,and rotate flexibly,which widly used engineering machinery, construction machinery, metallurgy mining machinery, shipping port machinery, environmental machinery, light industrial machinery, petrochemical machinery, engineering vehicles, military devices, food machinery, canning nachinery, car parking systems etc.

Since the light slewing bearing is so critical, careful maintenance is necessary. More than 96% of slewing ring bearing failures are due to surface-originated lubrication problems, contamination, overloading, and improper installation and mounting fits. These surface failures occur much earlier than classical fatigue failures and are less predictable.
