The external tooth three-row cylindrical roller slewing bearing, categorized under the 13 series, is a crucial component in heavy machinery. This robust bearing is constructed from an inner ring, outer ring, three rows of rollers, a cage, and a sealing device, ensuring superior performance and reliability. Its design features separate upper, lower, and radial raceways, with two horizontal sets of rollers supporting axial loads and overturning moments, while a vertical set of rollers manages radial loads effectively. The external teeth on the outer ring enable efficient rotational motion through precise gear meshing. As a leading manufacturer in China, our factory specializes in the production of high-quality slewing bearings, catering to the needs of various industrial applications. We are proud to be prominent suppliers in the market, delivering durable and efficient solutions for your heavy machinery requirements
