About Slewing Bearings
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.
