Slewing bearing is a large bearing used in heavy machinery to enable smooth rotation between two components. It consists of an inner ring, an outer ring, rolling elements, and sometimes gears. It supports axial, radial, and moment loads and is commonly found in cranes, excavators, wind turbines, and industrial robots. Slewing bearings ensure controlled rotation and transfer loads between stationary and rotating structures.

Super-precision axial-radial cylindrical roller bearings are commonly used to support rotary tables, indexing heads and multi-spindle heads on machining centres. Efant manufactures super-precision axial-radial cylindrical roller bearings for shaft diameters from 80 to 850 mm. Their internal design, together with close tolerance manufacturing processes, enables these bearings to attain radial run-out better than, and axial run-out close to, P2 tolerance class.

Cross roller bearing is a special type bearing with split inner ring and rotating outer ring. It has excellent rotation accuracy, simple operation and installation, and bears large axial and radial loads.
