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.

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 |
