Wide Welded Steel WD110 Chain | DCC
DCC WD110 Chain is a reliable welded steel drag chain designed for bulk material handling in drag conveyor systems. With a 152.4mm pitch and wide 231.5mm inner section, it enables efficient transport of materials like wood chips, grain, or sawdust at 16.9kg/m. Available in WDH110 (220KN tensile strength) for heavy-duty use and WDR110 (170KN) for standard applications, it ensures smooth operation in abrasive environments.

Key Features of DCC WD110 Chain
● Wide Pushing Area Design: 231.5mm inner width and 263.5mm outer width provide large contact surface for effective material dragging, reducing spillage and supporting high-volume conveyance at moderate speeds.
● Robust Sidebar Structure: 38.1mm sidebar height and 9.5mm thickness deliver rigidity and strength for continuous operation under load.
● Durable Pin and Bushing: 18.9mm pin diameter with D-sized bushing ensures smooth articulation and resistance to wear in demanding conditions.
● Welded Construction Quality: Automated robotic welding provides uniform weld points, enhancing overall chain integrity and fatigue resistance.
● Enhanced Wear Protection: High-frequency heat treatment on key components maintains performance in abrasive settings, extending operational life.
● Corrosion-Resistant Finish: Special coating and surface treatment protect against moisture and mild chemicals, suitable for indoor and semi-outdoor use.

FAQ
Q: How does WD110 differ from other welded drag chains?
A: WD110 offers a wide 231.5mm inner section for larger material volumes, with WDH110 providing higher 220KN strength for heavier loads compared to standard variants.
Q: What loads can the tensile strength handle safely?
A: With industry-standard safety factors, WDH110 supports substantial continuous loads in drag conveyors; WDR110 suits lighter applications.
Q: Can WD110 withstand abrasive or humid environments?
A: Standard coating offers good resistance; optional enhancements available for wet or highly abrasive conditions.
Q: What are the lubrication intervals for WD110?
A: Protective treatments allow extended intervals compared to untreated chains, based on operating conditions.
