The external tooth three-row cylindrical roller slewing bearing, part of the 13 series, is an essential component in heavy machinery applications. Manufactured in China, this high-quality slewing bearing consists of an inner ring, an outer ring, three rows of rollers, a cage, and a sealing device. The innovative design features separate upper, lower, and radial raceways, allowing it to efficiently manage various loads. The axial load and overturning moment are supported by two sets of rollers arranged horizontally along the axis, while a third set of rollers, positioned vertically, effectively handles the radial load. With external teeth located on the outer ring, this slewing bearing facilitates smooth rotational motion through engagement with gears. As a trusted supplier and factory of heavy machinery components, we ensure that our products meet rigorous standards of performance and reliability, making them ideal for a wide range of industrial applications.
