About WR78 Welded Steel Chain
WR78 welded steel chain belongs to WR series heavy-duty welded steel chains. It is fabricated by welding solid steel components, featuring robust one-piece construction, high tensile strength and excellent impact resistance.
Made of premium carbon or alloy steel, the chain delivers reliable wear resistance under harsh operating conditions. Its simple structure allows easy assembly, disassembly and maintenance.
This chain is widely used for bulk material conveying, including gravel, coal, ore, ash and agricultural products. It fits bucket elevators, apron conveyors and drag conveyors in mining, cement, agriculture and waste treatment industries.
Custom options like heat treatment and special surface treatment are available to extend service life. Our WR78 chain strictly follows industry standards, stable in performance and cost-effective for heavy-load continuous conveying tasks.
