what is a three row roller slew ring bearing?

Three-Row Roller Slew Ring Bearings are built with three independent rows of rollers to handle a mixture of axial, radial, and upsetting instant loads. The rollers are concerned with the best load-carrying capability. Three-row roller slew ring bearings are outstanding answers to requests where a high degree of stiffness is essential; however, they need rigid and precise mounting structures. As with all of our slew ring bearings, three-row roller slew ring bearings can be supplied with internal or external integral gearing.

Three-Row Roller Slew Ring Bearings reduce the bearing diameter by distributing the loads in unlike instructions to unlike rows of raceways and rollers, which makes the slewing ring more compact and recovers the load volume. A three-row roller slew ring bearing is well suited for lifting, mining, material transport, marine, and other engineering machinery.
