Wide Welded Steel WD120 Chain | DCC
DCC WD120 Chain is a robust welded steel drag chain engineered for medium to heavy-duty bulk material handling in drag conveyor systems. With a 152.4mm pitch and 222.5mm inner width, it supports efficient movement of materials such as chemicals, grains, or aggregates at 29kg/m. Available in WDH120 (360KN tensile strength) for demanding loads and WDR120 (310KN) for reliable standard operations, it ensures consistent performance in moderate abrasive environments.
Key Features of DCC WD120 Chain
● Medium Width Layout: 222.5mm inner width and 260.35mm outer width offer balanced contact area for effective material pushing, reducing slippage and enabling steady conveyance of medium-volume loads at moderate speeds.
● Strong Sidebar Construction: 50.8mm sidebar height with 12.7mm thickness ensures high rigidity and load-bearing capacity for ongoing operations in varied conditions.
● Reliable Pin and Bushing: 22.07mm pin diameter paired with A-sized bushing provides smooth joint movement and superior resistance to wear in particle-heavy settings.
● Automated Welding Excellence: Robotic welding process delivers uniform welds, enhancing structural reliability and fatigue endurance during prolonged use.
● Optimized Wear Protection: High-frequency heat treatment on essential components sustains chain functionality in moderately abrasive applications, extending maintenance cycles.
● Corrosion Defense Coating: Galvanization or protective surface treatment guards against humidity and light chemicals, making it suitable for indoor or partially exposed installations.

FAQ
Q: How does WD120 differ from WD480 or WD110 chains?
A: WD120 provides a medium 222.5mm inner width with high strengths (up to 360KN), bridging lighter WD110 for small volumes and wider WD480 for heavy bulks.
Q: What loads can the tensile strength accommodate safely?
A: Using standard safety factors, WDH120 manages significant continuous loads in drag systems; WDR120 suits moderately heavy duties.
Q: Is WD120 appropriate for mildly corrosive settings?
A: Enhanced coatings permit longer intervals than basic chains, varying by usage environment.
