Precision Forged Pin Chains - Power Transmission Chains For
Industrial Machinery & Equipment
Product Description
Our precision forged pin chains are manufactured to exact
tolerances for reliable power transmission in industrial machinery,
conveyor systems, and heavy equipment. Through advanced forging
processes, we deliver superior wear resistance, fatigue strength,
and load capacity compared to standard roller chains.
Key Features & Benefits
✔ Premium Materials – Made from alloy steel (4140/4340), carbon
steel, or stainless steel for optimal strength and corrosion
resistance.
✔ Precision Forging – Produces denser grain structure for higher
durability than cast or machined chains.
✔ High Load Capacity – Rated for heavy shock loads and continuous
operation in harsh environments.
✔ Custom Configurations – Available in single-strand,
double-strand, or multi-strand designs with custom pitches
(25mm–200mm).
✔ Extended Service Life – Heat-treated pins & bushings reduce wear
by 30–50% vs. standard chains.

Why Choose Our Forged Pin Chains?
✅ Higher Fatigue Resistance – Forged microstructure extends
lifespan under cyclic loads.
✅ Precision Fit – Tight tolerances (±0.05mm) ensure smooth
engagement with sprockets.
✅ Custom Solutions – Modify pitch, width, attachments, or coatings
for your needs.
✅ Rigorous Testing – Every batch undergoes load testing, hardness
checks, and metallurgical analysis.
FAQ
1. What makes forged pin chains superior to standard roller chains?
Higher Strength: Forged construction provides better fatigue
resistance (30–50% longer lifespan).
Greater Durability: Denser grain structure withstands shock loads
and abrasive environments.
Tighter Tolerances: Precision-fit pins/bushings (±0.05mm) reduce
sprocket wear.
2. What materials do you offer?
| Material | Properties | Best For |
|---|
| Alloy Steel (42CrMo) | High tensile strength (1200 MPa), heat-treatable | Mining, heavy machinery |
| Stainless Steel (316) | Corrosion-resistant, food-safe | Chemical/food processing |
| Carbon Steel (40Cr) | Cost-effective, quench-hardened | General industrial use |
3. Can you customize chains for unique applications?
Yes! We provide:
✔ Non-standard pitches (25–200mm)
✔ Special attachments (cleats, hooks, brackets)
✔ Coatings (hard chrome, zinc, nickel) for corrosion/abrasion
resistance
✔ X-ray inspected chains for safety-critical uses
