Three-Row Roller Slewing Bearing with External Gear
This type bearing features three separate rows of rollers — one axial row for axial loads, and two radial rows for radial and tilting moment loads. Each roller row is optimized for its specific load direction, delivering the highest load capacity and rigidity among all slewing bearing designs. The external gear is machined on the outer ring, enabling efficient, high-torque drive transmission. It is ideal for extreme heavy-duty applications such as large cranes, tunnel boring machines (TBMs), offshore platforms, and heavy-duty industrial turntables where maximum performance under severe conditions is required.
