Slewing bearing is a kind of large and medium sized bearing which can bear more comprehensive loads such as axial load, radial load and overturning moment. In general, the slewing bearing has its own installation holes, lubricating oil holes and sealing devices, which can meet the different needs of various types of hosts working under different working conditions.


On the other hand, the slewing bearing has the characteristics of compact structure, convenient guidance and rotation, easy installation and easy maintenance. It is widely used in heavy transportation equipment, such as lifting transport machinery, metallurgical machinery, mining machinery, construction engineering machinery, port machinery and automatic assembly line.

According to different structural forms, rotary bearing can be divided into four point contact ball bearing, double row of different diameter ball bearing, cross cylindrical roller slewing bearing and three row cylindrical roller combined bearing.

The above bearings are divided into toothless, outer and inner teeth according to whether they have teeth or teeth.

Slewing bearing can meet the needs of different working conditions under different load conditions according to different structural characteristics.

Among them, the four point contact ball bearing bearing has high dynamic load capacity, the cross cylindrical roller slewing bearing has a high static load capacity, and the three row cylindrical roller combination rotary bearing bearing leads to the high direction of the bearing because of improving the bearing capacity. All kinds of load are separately supported by different raceways and rollers. Under the same condition, the diameter of the bearing can be greatly reduced, so it has the characteristic of making the host more compact, and it is a kind of high bearing capacity slewing bearing.

Luoyang dragon horse Bearing Co., Ltd. (www.lmc.cn) is a joint-stock enterprise which produces and sells large, super large, substitutes for imported and non-standard special structural bearings. It mainly consists of split bearing, oil machinery special bearing, rotary bearing bearing, three row of roller bearing, cross roller bearing, double volley ball rotary bearing. Bearing bearing and so on. Welcome everybody to come to consult and choose and buy!
