Three-row Cylindrical Roller Slewing Bearing

The LYNB three-row cylindrical roller slewing bearing can carry axial load, tilting moment, and radial load 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, and the contact stresses are also decreased. Therefore, the load capacity of this design of slewing baring is the highest under the conditions of a bearing with the same boundary dimension. 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.

LYNB three-row cylindrical roller slewing bearing mainly consists of the components such as inner ring, outer ring, three rows of rollers, cage (spacing blocks), and a seal device etc.

The design applications where there is a large axial load, tilting moment, a larger radial load, or a low requirement for friction moment.

The basic structure of LYNB three-row cylindrical roller slewing bearing as below:

Without gear

External gear

Internal gear

 

▲   The design’s of all these slewing bearing are based on standard structures; LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNB Technical Center if you need any assistance in this area.
