Industrial 102NA Drop Forged Scraper Chain with Self-Lubricating UHMW Attachments
In the demanding sector of bulk material handling, the choice of traction medium is the deciding factor for system uptime. Hangzhou Ocean Industry Co., Ltd. introduces the 102NA Drop Forged Scraper Chain, a specialized mechanical solution designed to bridge the gap between extreme tensile strength and material-friendly handling. Unlike the painting line chain QXG250 conveyor chain or standard single guide conveyor chain models used for overhead transport, the 102NA is engineered for the rigors of drag and submerged conveyors where material is moved through enclosed troughs.
This heavy duty conveyor chain is forged from high-alloy steel and undergoes a rigorous vacuum quenching process to ensure structural integrity under a breaking load of 150 KN. By integrating Ultra-High Molecular Weight Polyethylene (UHMW-PE) scraper flights, we have effectively transformed a high-friction "metal-on-metal" process into a smooth, self-lubricating "polymer-on-metal" slide. This innovation not only drastically reduces the energy required by the drive motor but also provides a "quiet operation" profile essential for indoor processing plants. As a cornerstone of a modern industrial conveyor system chain, the 102NA series offers a rivetless architecture for rapid, tool-free maintenance in the most abrasive environments.
| Chain No. | Pitch (P) | Sidebar (T) | Sidebar (H) | Pin (G) | Pin (F) | Avg. Breaking Load | Avg. Weight |
|---|---|---|---|---|---|---|---|

Core Product Features & Advantages
Drop-Forged Link Resilience
Links are manufactured using 40Cr or 45Mn alloy steel, ensuring the internal grain flow is aligned for maximum resistance to fatigue and shock.
01
Low-Friction UHMW Scrapers
The polymer flights possess a coefficient of friction as low as 0.15, protecting the conveyor trough from wear and reducing total system drag.
02
Rivetless Maintenance Design
The 102NA "T-head" pin design allows for manual assembly and disassembly without the need for hydraulic presses or grinding.
03
Acoustic Insulation
The use of UHMW attachments dampens mechanical vibration, providing a noise reduction of up to 15dB compared to all-steel scrapers.
04
Corrosion & Impact Shield
The forged links are treated with an anti-oxidant layer, while the UHMW flights resist chemical attack from moisture and acidic bulk materials.
05
Selection & Environmental Guidelines
Engineering Selection Advice (Load vs. Speed)
When integrating the 102NA into an industrial conveyor system chain, the most critical factor is the "Chain Pull" calculation. Hangzhou Ocean Industry recommends a safety factor of 10:1 for standard drag conveying. While a fixed hanging plate chain for painting lines is judged by vertical load, a scraper chain is judged by horizontal resistance. If your material is highly adhesive (e.g., wet sludge), increase the motor torque by 25% to overcome the initial static friction of the UHMW flights on the trough floor.
Applicable Environmental Conditions
Thermal Dynamics: Rated for continuous operation in temperatures ranging from -40°C up to +80°C.
Atmospheric Resistance: Ideal for high-humidity grain silos, chemical fertilizer plants, and dusty coal handling facilities.
Velocity Profile: Best suited for stable, constant-velocity travel between 0.1 m/min and 0.5 m/min.
Working Principle: The Low-Friction Drag Cycle
The 102NA operates as a continuous loop at the base of a rectangular trough. As the drive sprocket engages the forged links, the chain moves forward, and the attached UHMW scrapers "drag" the bulk material forward. This volume displacement method is highly efficient for grains, minerals, and sludge. Because the single guide conveyor chain logic is applied to keep the chain centered, the scrapers maintain a tight seal with the trough floor, ensuring a 99% discharge rate at the end of the conveyor loop.
Industrial Application Scenarios
Agriculture & Silo Management: Moving massive volumes of corn and soybean in high-capacity grain elevators.
Wastewater Treatment: Scraping heavy grit and sludge in primary settling tanks where chemical resistance is mandatory.
Biomass & Energy: Transporting wood chips and fine coal in dust-tight, enclosed industrial conveyor system chain layouts.
