Industrial-Grade Forged Chains: Suspension, Conveyor & Drive Applications
Product Overview
Our industrial-grade forged chains are engineered for maximum strength, durability, and reliability in the most demanding material handling, mining, and processing environments. Manufactured through precision closed-die forging, these chains outperform conventional welded and cast alternatives with 3–5× longer service life, superior load capacity, and enhanced fatigue resistance.
Key Features & Benefits
✅ Unmatched Strength & Durability
Material: High-grade alloy steels (42CrMo4, 20MnCr5, custom options)
Tensile Strength: 900–1,400 MPa (heat-treated)
Impact Toughness: 50J @ -20°C (low-temperature performance)
✅ Engineered for Extreme Conditions
Abrasion Resistance: Tungsten carbide overlay available (+400% wear life)
Corrosion Protection: QPQ nitriding, HVOF coating, or hot-dip galvanizing
Temperature Range: -50°C to +300°C (special alloys for extreme environments)
✅ Precision Manufacturing
Closed-Die Forging: Optimized grain flow for fatigue resistance
Dimensional Accuracy: ±0.3mm (ensures smooth system integration)
Surface Hardness: HRC 55–60 (induction-hardened wear surfaces)
✅ Smart Customization Options
Attachment Styles: Cleats, flight bars, custom brackets
Maintenance Features: Self-lubricating bushings, quick-release links
IoT-Enabled: RFID or strain gauge embedded for predictive maintenance
Product Range & Specifications
| Chain Type | Suspension Chain | Conveyor Chain | Drive Chain |
|---|---|---|---|
| Diameter Range | 14–50mm | 18–60mm | 12–38mm |
| Working Load | Up to 250kN | Up to 400kN | Up to 300kN |
| Pitch Length | 40–150mm | 50–200mm | 25–120mm |
| Certifications | ISO 9001, CE, OSHA | MSHA, DIN 22258 | AGMA, ANSI B29.1 |
Applications
Suspension Chains: Overhead conveyors, trolley systems, assembly lines
Conveyor Chains: Mining scraper chains, bulk material handling, cement plants
Drive Chains: Heavy machinery, steel mills, port equipment
Product advantages
1. Ultra-High Load Capacity & Fatigue Resistance
✅ Extreme Load Performance
Tensile strength up to 1,400 MPa (42CrMo4 heat-treated)
5:1 safety factor, exceeding DIN 22258 standards
