Slewing bearing

Slewing bearings are large-sized precision bearings designed to support combined loads, including axial, radial, and moment forces, simultaneously. Featuring an integrated structure with mounting holes, gears, and sealing systems, they enable smooth rotation and reliable load transfer in compact designs. Slewing bearings provide excellent stiffness, high load-carrying capacity, and precise rotational performance, making them ideal for applications such as cranes, excavators, wind turbines, and industrial automation equipment. Available in single-row, double-row, and cross-roller configurations, these bearings ensure long service life, easy installation, and stable operation under demanding working conditions.
