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.

1.       four point contact ball slewing ring bearings
2.       double row ball four point contact slewing ring bearings(same diameter ball; different diameter ball)
3.       cross roller slewing ring bearings
4.       triple row cylindrical roller combined slewing ring bearings
5.       ball roller combined slewing ring bearings
6.       light flanged slewing ring bearings
