Three row roller slewing bearing is also called turntable bearing

Three row roller slewing bearing is also called turntable bearing, and some people also call it: rotating bearing, slewing bearing.
Three row roller slewing bearing is a new type of mechanical parts that have gradually emerged worldwide in the past forty years. They are composed of inner and outer rings, rolling elements, etc.
Three row roller slewing bearing is a large bearing that can bear comprehensive loads and can bear large axial, radial loads and overturning moments at the same time.

Three row roller slewing bearing is generally equipped with mounting holes, internal or external gears, lubricating oil holes and sealing devices, so that the main engine design structure can be compact, easy to guide and easy to maintain.
Three row roller slewing bearing have four series: gearless, external and internal gear four-point contact ball bearings, double-row angular contact ball bearings, cross cylindrical roller bearings, cross tapered roller bearings and three-row cylindrical roller composite bearings. Among them, four-point contact ball bearings have higher static load capacity, cross cylindrical rollers have higher dynamic load capacity, and the pre-interference of cross tapered roller bearings can make the bearings have greater support rigidity and rotation accuracy.

The three row roller slewing bearing leads to the height of the bearing due to the increase in load-bearing capacity. Various forces are borne by different raceways. Therefore, under the same force, the bearing diameter can be greatly reduced, so it has the characteristic of making the main engine more compact.
Three row roller slewing bearing is widely used in large slewing devices of lifting machinery, mining machinery, construction machinery, port machinery, ship machinery, high-precision radar machinery, missile launchers, etc. At the same time, we can also design, develop and produce various special structure slewing bearings according to the specific requirements of users.
