Ball Slewing Bearing

slewing bearings is a kind of large-size bearing with special configuration which can bear axial load, radial load and tilting moment. generally, a slewing bearing has mounting holes, lubricating holes and sealing system which can meet different needs of different machines under different working conditions.
our slewing bearings include the following types:
4 point contact ball slewing bearing;
double-row angular contact ball slewing bearing;
crossed cylindrical roller slewing bearing;
three-row cylindrical roller slewing bearing;
ball and cylindrical roller combined slewing bearing.
these bearings can be divided with no-gear, external gear and internal gear.
slewing bearings can meet different needs of different machines under different loads as per their types. 4 point contact ball slewing bearing can carry higher dynamic loads; crossed cylindrical roller slewing bearing can carry higher static loads; the preload of crossed tapered roller slewing bearing can make it better support rigidity and higher rotation accuracy; three-row cylindrical roller slewing bearing can carry large load.
