/ Single row roller slewing bearings

Roller Slewing Bearing

1.Product Introduction: Slewing bearings with rollers as the core load-bearing components, having strong load-bearing capacity and impact resistance, suitable for large equipment under heavy loads and harsh working conditions.
2.Structure Type: It has a thick-wall annular integrated structure. The inner and outer rings have double raceways, with built-in single-row or multi-row cylindrical or tapered rollers, steel cages, heavy-duty dust-proof seals, and the mounting holes are suitable for high-strength bolts.
3.Size Range: Outer ring diameter: 500 - 3000mm, inner ring diameter: 450 - 2850mm, height: 25 - 100mm.
4.Material: Inner ring /outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile，fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Port cranes, metallurgical equipment, large wind power main units, heavy-duty mining machinery.
6.Key Inspection Items: Roller assembly clearance, anti-overturning moment performance, dust-proof performance of seals.
