Slewing bearing is a kind of large bearing, which is used in many machinery and equipment now. There are many types of slewing bearings and their structures are also different. There are four-point contact ball bearings, double row angular contact ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and Three-row cylindrical roller combined bearing and other structural types. Among them, the four-point contact ball bearing has a higher static load capacity; the crossed cylindrical roller bearing has a higher dynamic load capacity; the crossed tapered roller bearing can make the bearing have greater support rigidity and higher rotation through pre-interference precision.
