The slewing bearing is normally composed of two rings made of high resistance steel, and their relative rotating motion is allowed by the creation of raceways hosting the rolling elements, which can be balls or cylindrical rollers. The roller raceways are the structural heart of the bearing and require the major attention during the production cycle. An induction hardening treatment must be applied on raceways in order to increase their hardness both on the surface and in depth. This allows the bearing to endure the huge loads it is usually subject to, ensuring structural integrity over time. So, getting the more structural data or processing diagram, visiting us
