Slewing bearing ,slewing ring bearing or turntable bearing

Slewing bearing is a kind of large bearing that can bear comprehensive load, and can bear large axial and radial load and overturning moment at the same time. The 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, easy to guide and easy to maintain. LYTBZ slewing bearing has four series of toothless, 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-row cylindrical roller composite bearings, of which four-point contact ball bearings have higher static load capacity, cross cylindrical rollers have higher dynamic load capacity, The pre-interference of cross-tapered roller bearing can make the bearing have greater support rigidity and rotation accuracy. The bearing diameter of the three-row cylindrical roller combined bearing can be greatly reduced under the same load because the bearing capacity is increased to the bearing height and various forces are borne by different raceways. Therefore, the main engine is more compact is characterized by a high bearing capacity of the slewing bearing. slewing bearing is widely used in lifting machinery, mining machinery, construction machinery, port machinery, Marine machinery and high-precision radar machinery and missile launchers and other equipment on the large slewing device. At the same time, can also design, develop and produce various special structure slewback bearings according to the specific requirements of users.

Slewing bearings are widely used in real industry, known as: "machine joints", and their main applications are widely used in: Truck 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.

The characteristics of slewing ring bearing

1. High load carrying capacity.

2. High stiffness for rigid bearing application.

3. Low friction.

4. Long service life.

5. Surface protection and corrosion resistance.

6. Integration of additional features, including: Driving mechanism. Control devices. Lubrication systems.
