Double row ball slewing ring bearing
1. Introduction of LYHY double row ball slewing bearings
LYHY 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.
The double row ball slewing bearing has three seat-rings. The steel balls and the retainers may be directly arranged into the upper and lower racers. Two rows of steel balls with different diameters are fitted according to the force. Such open type fitting is extraordinary convenient, the loading angels at upper and lower races are 90°which can carry both of the axial force and capsizing moment. When the radial force is larger than 1/10 of the axial force, the races should be newly designed.
Double row ball slewing bearing has three different types:
Double row ball slewing bearing with no gear
Double row ball slewing bearing with external gear
Double row ball slewing bearing with internal gear
Double row ball slewing ring bearings have following features:
Larger dimension of axial and radial and compact structure.
Double row ball slewing ring bearings are widely used in Tower cranes which require working radius over medium range, auto crane and loading (unloading) machinery.

Slewing ring bearing is also called slewing ring, slewing 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 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.
2.1 Slewing ring bearings have different types as per different structures, here below is what we offering now:
Single row ball slewing ring bearings
Double row ball slewing ring bearings
Crossed roller slewing ring bearings
Triple row roller slewing ring bearings
Flange slewing ring bearings
2.2 The above slewing ring bearings can also be divided into three different types as per different transmissions:
Slewing ring bearings with no gear
Slewing ring bearings with external gear
Slewing ring bearings with internal gear
Slewing ring bearings have more features: compact structure, reliable guide, simple installation, and easily maintenance
Slewing ring bearings can be widely used in lifting & transport machinery, mining machinery, construction machinery, port hoisting machinery, port oil transfer equipment, onshore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generator, other construction and industry machines or equipments and other large rotary device.
Here below are some of the slewing bearings we usually produced, if you have any requirement on slewing ring bearings, please be free to contact me.
