Tri-row culindrical roller combined slewing bearing

As a professional triple row cylindrical roller combined slewing bearing manufacturer in China, we mainly provide: internal gear type triple row cylindrical roller combined slewing bearings, external gear type triple row cylindrical roller combined slewing bearings and no gear type triple row cylindrical roller combined slewing bearings.

Characteristics of Triple Row Cylindrical Roller Combined Slewing Bearing

1. Our triple row cylindrical roller combined slewing bearing has super high carrying capacity.

2. It consists of three bearing rings. The adjusting spacer between upper bearing ring and lower bearing ring can adjust the axial internal clearance.

3. Upper row rollers and lower row rollers are distributed horizontally, so as to support the axial forces and tilting moments from two directions. While radial force is supported by the third row rollers that are vertically distributed.

4. Since our triple row cylindrical roller combined slewing bearing is firm in structure and large in axial dimension and radial dimension, it is quite suitable for use in heavy duty machinery, such as bucket-wheel excavators, wheel cranes, ship cranes, port cranes, molten steel operating platforms, and so on.


The three row cylindrical roller combined slewing bearing can carry axial load, tilting moment, and radial load all at the same time. Compared to cross-cylindrical roller slewing bearing the load of each roller is reduced. Point contact is changed into line contact compared with that of a double row ball slewing bearing, the contact stresses are also decreased. Therefore, the load capacity of this design of slewing bearing is the highest under the conditions of a bearing with the same boundary dimensions. Axial load and radial load for this design are loaded by different rollers, in which the axial load and tilting moment are loaded by two groups of horizontal placed rollers, the radial load is loaded by one group of vertical placed rollers. The three row cylindrical roller combined slewing bearing mainly consists of the components such as inner ring, outer ring, three rows of rollers, cage (spacing blocks), a seal device etc. This slewing bearing design is suitable for most applications where a large axial load and tilting moment, or with a larger radial load, or with a low requirement for friction moment.
