320 325 332 340 350 Triple row roller bearing

320 325 332 340 350 Triple row roller bearing

The three-row roller slewing bearing series with external gear is engineered for extreme-duty rotating applications where maximum load capacity, superior rigidity, and long-term reliability are non-negotiable. This design utilizes three independent rows of cylindrical rollers, each dedicated to a specific load direction, delivering performance levels that single-row and double-row configurations cannot match.



Application Areas：

Extra-heavy cranes and construction machinery

Large-scale excavators and mining equipment

Wind turbine yaw and pitch systems

Heavy-duty radar and antenna platforms

Industrial heavy turntables and rotary tables

This bearing series comprises an inner ring, an outer ring with integral external gear teeth, and three separate rows of cylindrical rollers positioned in dedicated raceways. One row manages axial loads in one direction, a second row handles axial loads in the opposite direction, and a third row supports radial loads. This clear separation of load paths allows each roller row to be precisely sized and oriented for its specific function, ensuring efficient load transmission and minimal stress concentration.

The external gear is formed directly on the outer ring, providing a robust interface for direct pinion drive engagement without requiring additional gear components. Both rings feature drilled mounting holes for secure bolted attachment to the machine structure, simplifying installation and alignment.
