/ Three-row cylindrical roller slewing bearings

slewing ring turntable

1.Product Introduction: Turntable devices integrating slewing bearings, including slewing bearings and turntable surfaces, which can be directly installed with equipment to achieve 360° slewing, and are convenient for installation.
2.Structure Type: It consists of slewing bearings (ball-type or roller-type) and steel turntable surfaces (with mounting holes). The surface is welded or bolted to the outer or inner ring of the slewing bearing.
3.Size Range: Turntable diameter: 500 - 3000mm, surface thickness: 10 - 30mm, slewing bearing height: 15 - 100mm.
4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Logistics turntables, rotating platforms of amusement equipment, slewing platforms of construction machinery, exhibition turntables.
6.Key Inspection Items: Flatness of the turntable, slewing accuracy, welding strength of the surface.
