/ Single row roller slewing bearings

mini excavator swing bearing

1.Product Introduction: Customized to fit 1 - 6 tons of small excavators, it can withstand the impact loads and overturning moments during operation, is waterproof and dustproof, and suitable for outdoor complex working conditions.
2.Structure Type: It has a compact annular shape. The inner ring is connected to the machine body, and the outer ring is connected to the slewing platform. It has built-in single-row or double-row steel balls. The raceways are quenched, with double seals on the outside (rubber + dust ring), and the hole positions precisely match the machine body.
3.Size Range: Outer ring diameter: 400 - 1500mm, inner ring diameter: 350 - 1350mm, height: 20 - 60mm.
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: 1 - 6 tons of small excavators (for connecting the slewing platform), small loaders, micro engineering machinery.
6.Key Inspection Items: Quenching hardness (HRC55 - 60), anti-sediment performance of seals.
