Double row ball slewing ring bearing1. 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.2. Structure:Double row ball slewing bearing has three different types:Double row ball slewing bearing with no gearDouble row ball slewing bearing with external gear Double row ball slewing bearing with internal gear  3. Features:Double row ball slewing ring bearings have following features:Larger dimension of axial and radial and compact structure. 4. Application: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 Bearing1. Introduction of LYHY slewing ring bearingsLYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball slewing ring bearings, roller slewing bearings and precision slewing ring bearings as per customer's different technical requirements.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. Structure2.1 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 bearingsCrossed roller slewing ring bearings Triple row roller slewing ring bearings Flange slewing ring bearings2.2 The above slewing ring bearings can also be divided into three different types as per different transmissions:Slewing ring bearings with no gearSlewing ring bearings with external gearSlewing ring bearings with internal gear3. Features: Slewing ring bearings have more features: compact structure, reliable guide, simple installation, and easily maintenance4. Application: 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.
