Three-Row Roller Slewing Bearing with Internal Gear
This bearing incorporates three independent rows of rollers — one axial row for axial loads and two radial rows for radial and tilting moment loads — providing the highest load capacity and structural rigidity among all slewing bearing designs. The internal gear is integrated into the inner ring, allowing a compact, space-saving drive arrangement with built-in gear protection. This design is ideal for heavy-duty, harsh-environment applications such as large excavators, offshore cranes, tunnel boring machines (TBMs), and port handling equipment, where maximum load performance and a protected gear interface are required.
