The 130 series is a three-row roller slewing bearing without gear teeth on either ring. This gearless series is engineered for extreme heavy-duty applications where maximum load capacity and exceptional rigidity are required, but where the drive system is best implemented externally rather than through integral gearing.
Large tower cranes and mobile cranes
Heavy-duty excavators and mining equipment
Wind turbine yaw and pitch systems
Large radar and antenna positioning systems
Heavy-duty industrial turntables

The 130 series bearing consists of an inner ring, an outer ring, and three rows of cylindrical rollers arranged in separate raceways. Both rings are free of gear teeth, making this a gearless configuration. The three rows are dedicated to handling specific load directions: one row supports axial loads in one direction, a second row supports axial loads in the opposite direction, and the third row supports radial loads. This independent load path design ensures each roller row is optimally sized and positioned for its designated function, delivering efficient load transmission and balanced performance under complex loading conditions.
The omission of gear teeth simplifies the ring geometry, reduces manufacturing costs, and makes the bearing easier to handle and install. Both rings are provided with mounting holes for straightforward bolted attachment to the machine structure.
