Slewing Bearing (Turnable Bearing) introduction:

   Slewing bearing (Turnable bearing) is a large-scale integrated load bearing, which can bear large axial load, radial load and overturning moment. Slewing ring bearings are generally of inner gear or outer gear, mounting holes, lubrication holes (oil holes), and seals, which can make the host be an compact design, easy to guide and maintain.Slewing bearings can be nongeared, internal gear and external gear.

The slewing bearing types are mainly as follows:1. Four-point contact ball slewing bearings2. Double-row different diameter ball slewing bearings3. Crossed cylindrical roller slewing bearings4. cross-tapered roller slewing bearings5. Triple-row cylindrical roller slewing bearings

Slewing bearings are widely used in industry and known as "the machine joints"
Slewing Bearings  Characteristics	1. Four-point contact ball slewing bearings are of high static load capacity, which are able to bear radial load, axial load and overturning moment
	2. Crossed cylindrical roller slewing bearings mainly bear larger axial load and also carry overturning moment. Crossed cylindrical roller bearings are of dynamic load capacity
	3. Cross-tapered roller bearings' pre-interference can can support a greater rigidity and rotary accuracy.
	4. Double-row different diameter ball slewing bearings are able to bear greater overturning moment, which bear load mainly at axial.
	5. Three-row cylindrical roller bearings increase the carrying capacity and can bear a more heavy load,because forces are beared by diffenrent raceway. So three-row cylindrical rollerbearing is a high carrying capacity of slewing bearings.In the same force cases, because the diameter of the bearing can be greatly reduced.Hence the characteristics of the host is more compact
Major Applications	Lifting machinery, Mining machinery, Construction machinery, Port machinery, Ship machinery, Missile launchers, High-precision Radar machinery, wind turbine, wind power generation equipment and Other large rotary device.
	Such as:  Crane bearings, Marine crane bearings, Port crane bearings, Offshore crane bearings, Ferris wheel bearings, Excavator bearings, Filling machine bearings, Ship unloader bearings,Stacker bearings, Robot bearings, Wind turbine bearings, Onshore bearings,  Offshore bearings, Ladle turret bearing, Shield bearing, Military industry bearings, Missle launchers, Radar antena bearings,
