Product Description
Combination Chain
Product Description
Combination Chains used extensively in the cement.paper and pulp, quarrying, and mining industries for elevating and conveying a wide variety of CZPT and non-abrasive materials.It is also finding many uses in general industrial assembly conveyors. It is not recommended for drive chain.The construction of our Combination Chain can be either cottered or riveted. Cottered is normally considered standard. Pins have flat areas at their ends, which lock into the appropriately punched sidebars, preventing pin rotation during chain operation.
All pin holes are clean-cored for smooth bearing surfaces and are dimensioned for proper pin clearance. Industry dimensional standards are rigidly maintained and this chain may be interchanged with links of other manufacturers. Pitch sizes range from 1.631 to 6.050 inches; tensile strength range ex1ends from 12,150 to 67,500 pounds.
All our factory’s Combination block links except C55 and C55L have elliptical barrels. This adds extra metal where the sprocket to chain contact causes most chain wear.
Attachments are available in many of the pitch sizes for a wide range of applications.
Combination links are symmetrical and may therefore be operated in either direction of travel. Brutaloy and cast steel sprockets are available for each pitch size.
Our Promal (Duramal) chains have heat treated pins with Promal (Duramal) block links. Super Promal ( Duramal) chains have heat treated pins and sidebars with Promal ( Duramal) block links.Chains are also available with block links of the hard Promal (Duramal).

How do cast chains handle high-torque and heavy machinery applications?
Cast chains are well-suited for high-torque and heavy machinery applications due to their inherent strength, durability, and ability to withstand substantial loads. Here’s how cast chains excel in handling such demanding conditions:
- Material Strength: Cast chains are typically made from high-quality alloy steel or other robust materials, providing excellent tensile strength and resistance to wear and fatigue. This inherent material strength allows them to handle the high forces and torque experienced in heavy machinery applications.
- Heat Treatment: Cast chains undergo specific heat treatment processes to further enhance their strength and hardness. This ensures that the chains can withstand the stress and forces encountered in heavy machinery operations.
- Large Pitch Size: Cast chains are available in various pitch sizes, allowing for customization to suit the specific requirements of heavy machinery. Larger pitch sizes accommodate higher loads and torque, making them suitable for heavy-duty applications.
- Surface Protection: Cast chains often feature coatings or plating to protect against corrosion and wear. This is especially crucial in heavy machinery applications where the chains may be exposed to harsh environments or abrasive materials.
- Impact Resistance: Heavy machinery applications may involve sudden starts, stops, or changes in direction, leading to impact forces on the chains. Cast chains are designed to handle such shock loads and provide reliable performance even under dynamic conditions.
- Precision Engineering: Cast chains are manufactured with precision engineering techniques to ensure uniformity and consistent performance. This precision is vital for smooth operation and reduced wear in high-torque machinery applications.
Whether used in construction equipment, mining machinery, or industrial processing systems, cast chains offer a dependable power transmission solution for heavy-duty applications. Their ability to handle high-torque and heavy loads makes them a preferred choice in industries where ruggedness and reliability are paramount.

How do cast chains handle side loads and lateral forces?
Cast chains are designed to handle side loads and lateral forces effectively, making them suitable for applications where these forces are present. The robust construction and materials used in cast chains contribute to their ability to withstand such forces.
When subjected to side loads or lateral forces, cast chains distribute the load across their sturdy components, including the pins, bushings, and plates. The design and manufacturing process of cast chains ensure that they maintain their structural integrity and resist deformation even under challenging conditions.
The side plates of cast chains are typically thicker and more substantial than those of standard chains, which helps to enhance their resistance to bending and lateral stress. Additionally, the material properties, such as high tensile strength and hardness, provide cast chains with the ability to handle these forces without failure.
However, while cast chains can handle side loads and lateral forces well, it is essential to avoid excessive or sudden loads that could lead to premature wear or damage. Regular inspection and maintenance of the chains, including proper lubrication and tension adjustment, will help ensure their optimal performance and longevity in applications with side loads and lateral forces.

Can cast chains be used in high-temperature environments?
Yes, cast chains can be used in high-temperature environments, but their suitability depends on the specific material used to manufacture the chain and the temperature range of the application.
Cast chains are typically made from various materials such as cast steel, alloy steel, and stainless steel. Each material has its own temperature limits, and it is essential to choose the appropriate material that can withstand the operating temperature of the application.
For example, cast steel chains are generally suitable for use in high-temperature environments up to around 550°C (1022°F). Alloy steel and stainless steel chains can offer even higher temperature resistance, making them suitable for applications with temperatures exceeding 550°C (1022°F).
It is crucial to consult with chain manufacturers or experts to ensure the selected cast chain’s material can handle the specific high-temperature environment. Additionally, considering factors like lubrication and proper maintenance is essential to prolong the chain’s life and performance under high-temperature conditions.
Overall, with the right material and proper care, cast chains can effectively and safely operate in high-temperature industrial applications, such as furnaces, ovens, and other heat-intensive processes.
