The external tooth three-row cylindrical roller slewing bearing, classified under the 13 series, is an advanced component designed for heavy machinery. This bearing features a robust construction composed of an inner ring, outer ring, three rows of rollers, a cage, and a sealing device. The unique design includes separate upper, lower, and radial raceways that optimize load distribution. Axial loads and overturning moments are effectively managed by two horizontally placed roller sets along the axis, while a vertically positioned roller set handles the radial load, As a leading factory and supplier in China, we ensure that our slewing bearings provide exceptional rotational motion by integrating external teeth on the outer ring that mesh seamlessly with gears. These bearings play a crucial role in enhancing the performance and reliability of various heavy machinery applications, making them indispensable in the industrial sector
