Slewing bearings support heavy axial and radial loads, along with upsetting moments. They have inner and outer rings with mounting holes, lubrication channels, and gears. Induction-hardened raceways offer wear resistance, durability, and high load capacity. Precision-ground and heat-treated gear teeth ensure smoothness and accuracy. SunUs makes standard and custom slewing bearings, up to 2500mm in diameter, for versatile applications.
