Sell Three-row Roller Slewing Ring

Description

Design features: The bearings has three independent rows of rollers oriented normal to the direction of loads being transmitted through the ***** orientation is selected to optimize capacity, provide low frictional resistance and minimize deflection. The top and bottom rows of rollers transmit any opposing thrust loads and combine to transmit any moment loading, while the mid row transmits any radial ***** rollers, the seperator configuration used for each and the mating raceways are sized to meet load or other application requirements. In order to obtain these performance benefits, the supporting structures must satisfy higher stiffness and lower flatness requirements than those for similiar sized other series ring bearings. Gear teeth or other drive mechanisms can be provided on the inner or outter support ring, and the choice of hole pattern can be added for bearing retention. Applications: The series bearings have been used successfully in heavy duty applications requiring extra stiffness and capacity including: *Radar *Cranes *Excavators *Stackers and reclaimers *Heavy mill equipments
