Combination Slewing Bearing

Slewing Bearing

MATERIAL : Ring Material 42CRO or 50MN, Ball Material Chrome Steel,

Cage Material Nylon or 300 Series Stainless Steel

Combination slewing bearings are specialized bearings designed to handle axial, radial, and moment loads simultaneously, making them ideal for heavy-duty rotational applications. Featuring an integrated raceway and gear mechanism, they simplify assembly while offering high stiffness and smooth movement. Commonly used in cranes, excavators, wind turbines, and rotating platforms, these bearings ensure reliable 360° motion. Their compact design, high load capacity, and versatility make them essential for equipment requiring robust support with minimal structural complexity
