Why Cast Combination Chains Are Ideal for Harsh Industrial Environments
In heavy-duty industries such as agriculture, forestry, and wastewater management, durability and efficiency are essential. One of the most reliable solutions in material handling is the Cast Combination Chain, designed for tough environments, combining the strength of cast iron and steel.
What Is Cast Combination Chain?
A cast combination chain is an engineering-class conveyor chain that combines cast block links and steel sidebars or pins. These chains are known for their ability to handle abrasive, high-shock, and low-speed conditions, making them perfect for drag conveyors, grain elevators, and similar systems.
Key Features of Cast Combination Chains
Cast and Steel Components
The typical cast combination chain uses malleable or ductile cast iron for inner block links and heat-treated steel for sidebars and pins. This gives the chain: High wear resistance (cast), and High tensile strength and shock absorption (steel)
Durability and Abrasion Resistance
Cast block links can withstand high abrasion from dust, sand, grain, or chemicals. They're ideal for use in drag conveyors, scrapers, and elevating systems.
Symmetrical Design and Reversibility
Most cast combination chains, such as C55 and C188, are symmetrical, which allows them to operate bi-directionally. This feature increases flexibility in system design and reduces the need for chain repositioning.
Cast Combination Chain Types and Sizes
C60, C77, C102B, and C110 cast chains are used for more specific applications or older equipment systems.
Cast Combination Chain Materials and Construction
Malleable Cast Iron Block Links:
These links are precision-cast using malleable or pearlitic iron, making them strong yet resistant to brittleness — ideal for resisting abrasive media.
Heat-Treated Steel Sidebars and Pins:
The steel components are often heat-treated to increase hardness and fatigue strength, helping them withstand shock loading and extend service life.
Riveted vs Cottered Construction:
Cottered chains are easier to disassemble for maintenance.
Riveted chains offer more security and strength for heavy-duty or permanent installations.
For operations that prioritize durability and low maintenance, cast combination chains remain one of the top choices in industrial conveying systems. Cast combination chains are an excellent balance of strength, cost-efficiency, and wear resistance. Whether you're moving grain, bark, sludge, or minerals, these chains deliver reliable performance in challenging conditions.

Cast Combination Chain FAQs
What is the difference between C55 and C188 chains?
C188 is larger and stronger than C55. It has a higher pitch and is used in heavier-duty applications.
Are cottered chains better than riveted ones?
Cottered chains are easier to repair, while riveted ones are more secure and better for long-term use.
Can I customize cast combination chains with attachments?
Yes. We can offer custom flights, scrapers, and other attachments based on the chain type.
