The double flange slewing bearing is a versatile rotational component engineered for applications where both the inner and outer rings require flange-based attachment to the machine structure. This dual-flange configuration provides a symmetric mounting arrangement that simplifies installation, enhances structural stability, and ensures even load distribution across the bearing assembly.

This bearing series consists of an inner ring with an integral flange, an outer ring with an integral flange, and a single row of steel balls arranged between precision-ground raceways. The four-point contact ball geometry enables the bearing to support axial loads in both directions, radial loads, and tilting moments simultaneously within a single, compact row of rolling elements.
Both rings feature broad, flat flanges that serve as mounting surfaces, allowing direct bolted attachment to the respective machine structures without requiring additional adaptor plates or complex mounting brackets. This dual-flange design ensures accurate alignment and even load distribution across both rings, reducing stress concentrations and improving overall system stability.
