Slewing Rings
2.Structure Type: It consists of a fixed ring + a rotating ring + rolling elements + cages + seals. The rolling elements are single-row or double-row. The cages prevent collisions, and the seals protect the raceways.
3.Size Range: Outer ring diameter: 100 - 4000mm, inner ring diameter: 80 - 3800mm, height: 8 - 150mm.
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: Construction machinery, wind power, machine tools, amusement equipment, port machinery.
6.Key Inspection Items: Dimensional accuracy, slewing flexibility, running noise of rolling elements.
Industrial-Grade Slewing Rings Solutions for Heavy-Duty Applications
When your equipment operates under extreme loads, temperatures, or corrosive conditions, every component must perform flawlessly. Slewing Rings (also called slewing bearings) are the backbone of rotating systems in industries like metallurgy, mining, and port machinery. At LUOYANG INNO BEARING, we engineer these critical components to handle 150°C+ heat, 50,000kN loads, and harsh environments while delivering 30% faster lead times than industry standards.
Built for Extreme Conditions: Industry-Specific Designs
Metallurgy & Smelting
-
150°C Heat Resistance: Special alloy coatings prevent thermal deformation during continuous furnace rotations.
-
High Axial Load Capacity: 30% stronger axial load handling vs. standard models for ladle turret systems.
Mining & Material Handling
-
Anti-Shock Design: Reinforced raceways reduce deformation risks under 200-ton dynamic loads.
-
Corrosion Protection: Multi-layer sealing (IP68) and 1,200+ hour salt-spray resistance.
Port & Coastal Machinery
- Impact-Resistant Teeth: Laser-hardened gear teeth withstand 10,000+ hourly load cycles.
- Sand/Dust Protection: Labyrinth seals block abrasive particles in desert or coastal environments.

FAQ
1. How do your products handle 500°C+ temperatures?
Our metallurgical-grade rings use heat-resistant alloys and multi-layer coatings to prevent thermal expansion and maintain hardness.
2. What’s the lead time for a φ5000mm custom design?
15–20 days via modular production—50% faster than traditional methods.
3. Can you reverse-engineer rings for outdated machinery?
Yes! We use 3D scanning to recreate legacy products without original blueprints.
4. How do you ensure low noise in medical equipment rings?
P4-grade precision grinding and GCr15SiMn steel reduce vibration to <35dB.
5. Do you offer IoT integration?
Optional embedded sensors provide real-time load and wear data via our monitoring platform.
