Blog Entry: turntable bearing is a kind of can accept more of the axial load, radial load and overturning, and other comprehensive load, set support, rotation, transmission, fixed and so on many kinds of functions in one of the special structure of the large bearings. Usually, the wheel bearing itself there is a hole, lubricating oil and sealing devices, can satisfy all sorts of different operating under the working conditions of the different needs of host; On the other hand, wheel bearing itself has compact structure, convenient, easy installation guide rotation and easy to maintenance etc. Characteristics. slewing bearing is divided into no gear, gear and inside of the analysis, the four contact ball bearing, double row Angle contact ball bearing crossed cylindrical roller bearing, crossed tapered roller bearings and three rows composite cylindrical roller bearing four series, and four of them contact ball bearing has high static load ability, crossed cylindrical roller has high dynamic load ability, crossed tapered roller bearings preload surplus can make the bearing support more rigid and rotation accuracy, three rows of assembly cylindrical roller bearing capacity due to high, all sorts of forces from a different slot separate undertaking, so the same force, its bearing diameter can be greatly reduced, so the characteristics of the host more compact is a kind of high bearing capacity of rotation of supporting bearing. Of course, we can call it the slewing ring or slewing ring or turntable bearing , some people call it: rotation support, support swing. Widely used in lifting transportation machinery, mining machinery, construction engineering machinery, port machinery, wind power, medical equipment, radar and missile launchers and other large rotating device.
