excavator slewing bearing 1) High quality and good service 2) Durable 3) ISO9001 certificate 4) OEM service is available excavator slewing bearing1 Configuration of slewing bearings 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. 2 Packaging Before delivery, every slewing beairng is filled in rust-preventive lubricant on the inside surface, outerside surface and races, and then packed with plastic film, kraft paper and blue belt;3 Types:
