High-Quality Non-toothed three-row cylindrical roller slewing bearing Manufacturers, Factories

It is mainly composed of inner ring, outer ring, three rows of rollers, cage (separation block), sealing device and other components. The upper and lower as well as radial raceways of the three raceways are separate. The axial load and overturning moment are borne by the two sets of rollers placed horizontally along the axis, while the radial load is borne by the one set of rollers placed vertically along the axis. It is a pure bearing structure without any gears. The three-row raceway system constitutes its entirety. A completely independent drive system must be equipped. It is mainly used in situations where a large load needs to be borne and gear transmission is not required.
