Three-row Roller Slewing Bearings
The slewing ring of the three-row cylindrical roller slewing bearing has three races. The upper, lower, and radial raceways are separated. Therefore, each row of rollers can bear axial and radial loads respectively. It is one of the four products with the larger carrying capacity and is suitable for heavy machinery that requires a larger load.
