LYAJ Slewing bearing

Slewing bearing is a kind of large bearing which can bear comprehensive load, and can bear large axial and radial load and overturning moment at the same time. Slewing bearing is generally equipped with mounting holes, inner or outer gears, lubricating oil holes and sealing devices, which can make the main engine design compact structure, easy to guide, easy to maintain. LYAJ slewing bearing has four series of toothed, external and internal toothed four point contact ball bearings, double row angular contact ball bearings cross cylindrical roller bearings, cross tapered roller bearings and three rows of cylindrical roller composite bearings, among which four point contact ball bearings have higher static load capacity, cross cylindrical roller has high dynamic load capacity, The pre-interference energy of cross tapered roller bearing makes the bearing have greater support rigidity and rotation accuracy. Due to the improvement of bearing capacity to the bearing height, various forces are borne by different raceways of three-row cylindrical roller combination bearing, so the bearing diameter can be greatly reduced under the same stress. Therefore, it is a slewing bearing with high bearing capacity, which makes the main engine more compact. LYAJ slewing bearing is widely used in hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery and high-precision radar machinery and missile launchers and other equipment on the large slewing device. At the same time, LYAJ can also design, develop and produce various special structure slewing bearing according to the specific requirements of users.

Slewing bearing is widely used in real industry, known as: "the joint of the machine", its main application is widely used in: Automobile crane, railway crane, port crane, Marine crane, metallurgical crane, container crane, excavator, filling machine, as well as CT machine standing wave therapy instrument, navigation instrument, radar antenna base, missile launcher, tank, robot and rotating restaurant and so on.
