Detailed Product Description

Three-row roller slewing bearing has three seats, the upper, lower and radial raceways separate respectively, via which the load of each row roller can be determined exactly. It can bear various loads simultaneously and its load capacity is the largest one among all the models. Owing to large radial direction size and axle direction size, three-row roller slewing bearing is sturdy, high-precision, and especially suitable for heavy duty machines which require large working diameter, such as bucket wheel excavators, wheeled cranes, port cranes, tunnel boring machines, steel transporters, big tonnage truck cranes, big and heavy size spiral platforms etc.
