Bearing load calculation
Slewing Ring and slewing bearing have three independent rows of rollers with their normals aligned with the rotating roller ring load direction. Configuration maximizes load capacity, reduces friction, and minimizes bearing deflection.
The top and bottom rows of rollers can not only support bidirectional thrust loads, but also share moment loads when the middle row of rollers is subjected to radial forces. The arrangement of rollers and spacers in each row and the matching raceways are carefully designed to enable the bearing to meet the load or other application requirements.
To achieve these advantages, the support structure must be stiffer and flatter than that used in DZE or LYDZ series.
According to customer needs, gear teeth or other transmission mechanisms can be arranged on the inner ring or outer ring support structure, and the style of the axial and radial ring hole can also be specified by the customer.
Supply Capacity
Axial and radial ring bearings are manufactured to order to meet customer designs
Application Range
Rotating roller ring bearings are suitable for heavy-duty applications requiring extremely high
rigidity and performance, including:
●Radar
●Crane
●Excavator
●Stacker and reclaimer
●Heavy rolling mill
