Key Features & Benefits
1. Premium Materials & Manufacturing
High-Tensile Alloy Steel : Ensures maximum load capacity and wear resistance.
Precision Die-Forging Process : Provides consistent quality, high fatigue resistance, and extended service life.
Advanced Heat Treatment : Enhances hardness (40-50 HRC) while maintaining core toughness.
2. Heavy-Duty Construction
Forged Rollers & Bushings : Reduce friction and minimize elongation under load.
Precision-Machined Pins & Plates : Ensure smooth articulation and reliable power transmission.
Corrosion-Resistant Options : Available in galvanized, nickel-plated, or stainless steel for harsh environments.
3. Superior Performance in Critical Applications
✔ Transmission Chains – High-torque power transfer in drives, motors, and gearboxes.
✔ Conveyor Chains – Smooth material handling in drag, scraper, and bucket elevators.
✔ High-Speed & High-Load Systems – Engineered for low maintenance and long operational life.
4. Customization & Adaptability
Multiple Pitches & Sizes (e.g., ANSI, DIN, ISO standards or custom designs).
Special Attachments : For buckets, flights, or crossbars in conveyor systems.
Surface Treatments : Black oxide, zinc plating, or self-lubricating coatings.
