LYHY 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.
LYHY 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.
