TH TYPE NO TEETH

The TH type slewing bearing is indeed a versatile single bearing capable of simultaneously supporting axial loads, radial loads, and moments. This capability makes it highly suitable for various applications where there are combined loads and rotational movements. TH type slewing bearings are designed with raceways that allow for smooth rotation while efficiently distributing the loads across the bearing structure. This design not only ensures stability and durability but also reduces frictional resistance during operation. Therefore, the TH type slewing bearing is widely used in machinery and equipment such as cranes, excavators, wind turbines, and other heavy-duty applications where reliable load-bearing capacity under dynamic conditions is essential.
