Depending on Jiayu Bearing equipment and processes,we can design and manufacture large slewing bearing with integral rings with diameter of less 8 meters or segment rings if the diameter is over 8 meters.Most of slewing bearings choose 42CrMo.The raceway of rings are treated by improved medium frequency induction hardening to guarantee the hardness and depth of quenching.Strict defect checks are carried out so that material and machining defects can be found.
By optimizing the structure parameters and using effective tooling during processing.There are many large size NCN lathes and gear processing machines to control the deformation ohf the parts and make sure that they obtain high accuracy and the finished products can meet the standard.
