The double flange slewing bearing is a versatile rotational component designed to meet the demands of equipment where both the inner and outer rings require flange-based attachment to their respective structures. This symmetric design provides a practical and efficient mounting solution that simplifies assembly while ensuring reliable load transmission and structural stability.
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 feature broad, flat flanges that serve as mounting surfaces, allowing direct bolted attachment to the machine structure without requiring adaptor plates or complex mounting fixtures. The dual-flange design ensures accurate alignment during installation and promotes even load distribution across both rings, reducing stress concentrations and improving long-term reliability.
