1. Introduction of LYHY Slewing bearings
slew bearings 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, rotary bearings itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.
LYHY rotary bearing 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 slew bearing and to select the suitable slewing ring bearings.
2. Structure
2.1 slew bearings have different types as per different structures:
Single row ball slewing bearings
Double row ball turntable bearing
Crossed roller slewing bearings
Triple row roller slewing bearings
Flange rotary bearings
2.2 The above slewing rings 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
3. Features:
turntable bearing have more features: compact structure, reliable guide, simple installation, and easily maintenance
4. Application:
rotary bearing 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.
