Three Row Roller Slewing Bearing

LYXQL is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball bearings, roller bearings and precision bearings as per customer’s different technical requirements.
Slewing bearing is also called slewing ring, slewing ring bearing, turntable bearing, and rotary bearing. Slewing ring bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing rings 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 bearing itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.
LYXQL slewing ring bearings are usually used for low revolution while shaking and strained with an enormous axial force, moment and in some parts with radial force simultaneously.
Consequently the requirements for loading are stricter than ordinary bearings. If the selection of the slewing ring bearing has been wrong it will cause a great damage. Hence it is necessary to evaluate the exact forces acting on the slewing ring bearing and to select the suitable slewing ring bearings.

Three row roller slewing ring bearing has three seat-rings, which separate the upper, lower and radial raceway, via which the load of each row of the rollers may be specified. Thus it can carry different load simultaneously and its load capacity is the largest one of the four types

Structure:
Triple row roller slewing bearing has three different types:
Triple row roller slewing bearing with no gear
Triple row roller slewing bearing with external gear
Triple row roller slewing bearing with internal gear

Features  
Triple row roller slewing ring bearings have following features:
Larger axial and radial dimension, compact structure

Application
Triple row roller slewing rings are widely used in heavy-duty machines which require large working radius, such as bucket-wheel excavators, wheeled cranes, ship cranes, ladle turret, auto cranes etc.
