Ball Bearing Slewing Ring

1.Product Introduction: Slewing rings with steel balls as the rolling elements, commonly known as ball-type slewing bearings, featuring flexible slewing and low friction, suitable for medium and light-load slewing scenarios.
2.Structure Type: It has an annular shape. The inner and outer rings have single or double arc raceways, with built-in single-row or double-row steel balls, nylon or steel cages, rubber seals on both sides, and evenly distributed mounting holes.
3.Size Range: Outer ring diameter: 300 - 2500mm, inner ring diameter: 250 - 2350mm, height: 15 - 80mm.
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: Small excavators, amusement equipment, light logistics turntables, ordinary machine tools.
6.Key Inspection Items: Steel ball clearance, slewing flexibility, sealing and waterproof performance.

Product Description

FAQs

Q: How do you achieve a 15–20-day lead time for φ3000mm+ slewing rings?
A: Our modular production system pre-fabricates components, reducing assembly time by 40%.

Q: Can your slewing rings handle heavy impacts in port machinery?
A: Yes! Impact-resistant steel (GCr15SiMn) and reinforced cages absorb shock loads.

Q: Do you provide IoT-driven maintenance support?
A: Absolutely. We offer predictive maintenance plans with real-time bearing wear monitoring.
