Slewing bearings are soccer ball or cylindrical roller bearings that can support axial, radial and moment a lot operating either singly or in combination together with in any direction.

Slewing bearing can simultaneously support larger combined load which include axial load, radial download and tilting moment or anything else. Basic slewing bearing just about all has mounting holes, engine oil holes and sealing devices, can meet types of major machine running under many different circumstances. Additionally, slewing bearing have the features of compact structure, guiding rotation convenient, simple and easy installation and simple to maintenance, and commonly suited for large size slewing machines inside industrial sectors of executive, mining, metallurgy, residential wind it manually power generation, vessel, seaport, petroleum, food stuff, automobile, robotic, aerospace, chemical industry, light industry, medical machine, radar and war industry et cetera.

Based on diverse structural trend, slewing bearing is constantly divided into double strip four point ball slewing bearing, double row different size ball slewing bearing, several point contact ball slewing showing, cross cylindrical (taper) roller slewing bearing, ball and roller mixed slewing bearing and tri-row cylindrical roller combined slewing bearing and so on. Previously discussed slewing bearings may also be divided into various buildings of no gear form, external gear type and internal gear type according to whether are found gear and gear teeth distributing position.

In acquiescence with various structural feature, slewing bearing can correspondingly connect with main machine needs with various load conditions. In particular, four point contact soccer ball slewing bearing has better dynamic load capacity, corner cylindrical roller slewing showing has higher static load capacity. Tri-row cylindrical roller mixed slewing bearing is a variety of high carrying capacity slewing bearing, as a result associated with top raised carrying ability to direction of bearing peak, various loads might get correspondingly maintained by several raceways and roller packages, so raceway diameter greatly decrease under the same stress condition, they also have the character of getting major machine smaller sized.
