Double-Row Ball Slewing Bearing with External Gear
This bearing features two independent rows of balls arranged vertically, allowing it to support axial loads, radial loads, and tilting moments separately for higher load capacity and rigidity. The external gear is machined on the outer ring, enabling direct power transmission from a pinion. This design is ideal for heavy-duty applications such as tower cranes, stacker reclaimers, wind turbines, and large excavators, where high overturning moment and smooth rotation are required under harsh conditions.
