Slewing Ring Bearing
Slewing bearing is widely used in hoisting machinery, mining
machinery, construction machinery, port machinery, ship machinery
and equipment as well as high-precision radar machinery and missile
launcher equipment on the large slewing device. At the same time,
we can also design, develop and produce various special structure
slewing bearing according to the specific requirements of users.
Our different diameter ball slewing bearing has three seats
ring,the steel balls and the spaces may be directly arranged into
upper and lower raceways.two rows of steel balls with different
diameters are fitted according to the load.such open mode fiting
features are very convenience.the load angles of both upper and
lower race are90,which enable the bearingto bear large axial froce
and the overturning moment.when the radial force is larger than1/10
of the axial force .the raceways should be especial designed. the
axial dimension and radial dimension
of double-row ball slewing bearing are rather large,and the bearing
construction is sturdy
- Slewing bearing has four series: Four point contact ball bearings
without teeth, outer teeth and inner teeth, double row angle
contact ball bearing, cross cylindrical roller bearing, cross taper
bearing and three row cylindrical roller compound bearing.
- Four point contact ball bearings have higher static load capacity.
- Cross cylinder roller bearing has high dynamic load capacity, the
pre - interference of cross taper roller bearing can make the
bearing more rigid and accurate.
- Three rows of cylindrical roller combination bearing due to the
increasing of bearing height capacity , a variety of forces are
borne by different raceway, so the same force, the diameter of the
bearing can be greatly reduced, so that the main engine more
compact is a kind of slewing bearing with high capacity.
Slewing bearing is also called rotary bearing, some people also
called it: rotary support, cyclotron support.English name: slewing
bearing or slewing ring bearing, or turntable bearing. It is a
large bearing that can bear combined load, It can bear large axial
and radial loads and overturning moment at the same time. Slewing
bearing generally has mounting hole, internal gear or external
gear, lubricating oil hole and sealing device, so can make the
design structure of the main engine compact, easy to guide, easy to
