Excavator Slewing Bearing DX340

Slewing ring bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing ring bearings have their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions; On the other hand, slewing ring bearing itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.
Quantity:

The slewing bearing is a large-scale bearing, which looks like a plate, so it is called a slewing bearing. The slewing bearing can bear 3 kinds of bearing capacity at the same time, so it is widely used in the machinery industry.

The slewing ring is generally composed of an inner ring, an outer ring and rolling elements. The slewing bearing must rely on the outer ring or the inner ring as a support body when it is working, and then rely on the rolling of the rolling body to achieve rotation. Although the structure of the slewing ring is similar, there are still different models. According to current industry standards, there are five types of combined three-row cylindrical roller slewing bearings, crossed tapered roller bearings, crossed cylindrical roller bearings, four-point contact ball slewing bearings, and double-row angular contact thrust ball slewing bearings.

Therefore, the role of the excavator slewing support is obvious. The slewing support of the excavator realizes the rotation of the device through the action of friction and lubrication, which can drive mechanical propaganda in the excavator and provide supporting capacity.
