The double flange slewing bearing is a robust rotational component designed for equipment where both the inner and outer rings require direct flange mounting for structural integration. Featuring flanges on both rings, this design provides a balanced and practical mounting solution that simplifies assembly while ensuring reliable load transmission.
Compact crane turntables and winch drives
Aerial work platforms and lifting equipment
Solar tracking systems with space constraints
Light to medium-duty industrial turntables
Packaging and handling machinery
Equipment requiring flange mounting on both rings

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 are manufactured with wide, flat flanges that serve as mounting surfaces, allowing direct bolted attachment to the respective machine structures without requiring adaptor plates or additional mounting brackets. This dual-flange design ensures accurate alignment during installation and promotes even load distribution, reducing stress concentrations and extending bearing life.
