The introduction of slewing ring

Wheel bearings, slewing ring, also known, is a way to withstand large axial load, radial load and overturning moment of large self aligning ball bearings  Wheel bearings are generally with the mounting holes in the gear or external gear, lubrication holes and sealing devices, which enable the host compact design guide reliable, and easy maintenance.
     Wheel bearings with or without gear, external gear teeth and inside the four-point contact ball bearings, double row angular contact ball bearings, cylindrical roller bearings cross, cross tapered roller bearings and three-row cylindrical roller bearings and other kind of structure types. Where the four-point contact ball bearings with high static load capacity; Cross cylindrical roller bearings with high dynamic load capacity; cross tapered roller bearings make through preloaded bearings with a larger supporting rigidity and high rotation accuracy.
     Wheel bearings are widely used on lifting machinery, mining machinery, construction machinery, port machinery, shipbuilding, machinery and mechanical precision radar and missile launchers and other large rotary device.
Depending on the turntable bearing structure type structure can be broadly divided into the following types:
A four-point contact ball bearing turntable
2, double four-point contact ball bearing turntable
3. Cross cylindrical roller wheel bearings
4. Cross tapered roller wheel bearings
5, three-row cylindrical roller bearing turntable
