Large rolling bearings are currently manufactured in complex process chains. These manufacturing processes only make it possible to produce cost-intensive and generally heavy bearings. Innovative application possibilities are often in conflict with existing large bearing designs.



The new production technologies of gap profiling and gap profile bending are used to manufacture the large-size bearing. With the slit profiling process, a flat sheet is upset at the strip edges in several stitches, forming a flange on both sides. The last stitch of the gap profiling process is used for superimposed bending around the vertical axis to create the circular geometry. Necessary properties for running surfaces such as shape, strength and hardness are inherent to the manufacturing process. This bearing design enables various bearing types, such as rolling elements or contact angles
