Industrial Roller Chains: Conveyor, Agricultural, and Heavy-Duty Series
Donghua manufactures a comprehensive range of industrial chains to meet the demands of conveying, agricultural, and heavy-duty power transmission applications. From standard ANSI roller chains to specialized chains for extreme environments, our products are engineered for durability and performance. As a leading global chain manufacturer since 1991, we provide complete specifications to help you select the right chain for your equipment.
Understanding Our Chain Types
| Chain Category | Description & Applications |
|---|---|
| Heavy Duty Conveyor Chains | Designed for demanding applications like foundries and material handling. Ideal for unstable loads, transfer points, and crossing-over applications. Available in standard and oversized roller versions for reduced friction and better efficiency. |
| Agricultural Chains | Built for farm machinery such as combine harvesters, balers, and feeders. Resistant to dirt and debris. |
| Standard Roller Chains (ANSI/DIN) | For general power transmission and conveying. Available in single, double, and triple strand configurations. |

Key Features for Demanding Applications
Oversized Roller Options: Our chains are available with oversized rollers that extend past the link plates. This reduces friction when the chain slides on a surface, improving efficiency and wear life compared to standard roller chains that require guides.
Self-Lubricating Options: For applications like outdoor foundry conveyors handling hot forgings, we offer chains with self-lubricating features to withstand extreme conditions.
Self-Lubricating Options: For applications like outdoor foundry conveyors handling hot forgings, we offer chains with self-lubricating features to withstand extreme conditions.
Custom Configurations: We can customize roller width, spacing, and chain strength for specific loads (e.g., up to 5,000 lbs per bin) and applications like chain transfer conveyors and load/discharge systems.
