Double Flex Chain



What Is A Double Flex Chain?

A double flex chain, also known as a double-flexing chain, is a type of conveyor chain that is specifically designed to accommodate both horizontal and vertical flexing movements. It is commonly used in conveying systems where the chain needs to navigate around corners, curves, or sprockets with different radii.

The main feature that distinguishes a double flex chain from a standard conveyor chain is its ability to flex in multiple directions. It achieves this flexibility through its unique construction, which includes specially designed side plates and pins.


How To Choose The Right Double Flex Chain?

When choosing a double flex chain, there are a number of factors to consider, including:

  • The load that the chain will be handling: The chain must be able to handle the load that it will be subjected to. If the chain is overloaded, it can fail.
  • The speed at which the chain will be running: The chain must be able to operate at the speed required for the application. If the chain is running too fast, it can overheat and fail.
  • The environment in which the chain will be operating: The chain must be made from materials that are resistant to the environment in which it will be operating. For example, if the chain will be exposed to corrosive elements, it must be made from a corrosion resistant material.
  • The pitch of the chain: The pitch of the chain is the distance between the centers of two adjacent links. The pitch of the chain must be compatible with the pitch of the sprockets that it will be used with.
  • The width of the chain: The width of the chain is the distance between the inner and outer plates of the chain. The width of the chain must be wide enough to support the load that it will be handling.

Application of Double Flex Chain

Food Processing

Double flex chains are extensively used in food processing plants to convey food products through various stages of processing and packaging. Their flexibility allows them to navigate around equipment and machinery, ensuring efficient product movement.


Double flex chains are integral components of manufacturing assembly lines, transporting parts and materials through various stages of production. Their durability enables them to withstand heavy loads and harsh industrial environments.

Material Handling

Double flex chains are widely used in material handling applications, conveying materials such as sand, gravel, or grain. Their ability to handle heavy loads and operate in demanding environments makes them suitable for construction, mining, and agricultural applications.


Double flex chains are employed in packaging lines to transport and position packaging materials, such as boxes, bottles, and cans. Their ability to follow curved paths and conform to packaging shapes ensures accurate product placement and packaging integrity.


Double flex chains are essential in warehouse operations, moving goods and materials between storage areas, picking stations, and shipping docks. Their flexibility allows them to navigate around aisles and racking units, streamlining warehouse processes.

Automotive Industry

Double flex chains are utilized in automotive manufacturing plants to transport car components and assemblies along production lines. Their accuracy and reliability ensure efficient vehicle assembly and quality control.

Double Flex Chain Advantage

Enhanced maneuverability

Enhanced maneuverability

Double flex chains are capable of flexing in both directions, allowing them to navigate complex paths and follow intricate conveyor layouts. This makes them ideal for applications with multiple bends, corners, and obstacles.

Superior load handling

Superior load handling

Double flex chains can handle heavy loads with efficiency and reliability. They are typically made from strong and durable materials, such as carbon steel, stainless steel, or plastic, which can withstand significant stress and strain.

Types Of Double Flex Chain

There are a variety of different types of double flex chain available, depending on the specific application. Some of the most common types of double flex chain include:

  • Standard double flex chain: Standard double flex chain is the most common type of double flex chain. It is made from a variety of materials, including carbon steel, stainless steel, and plastic.
  • Heavy-duty double flex chain: Heavy-duty double flex chain is designed for use in applications where the chain will be subjected to heavy loads. It is made from stronger materials than standard double flex chain, such as high-strength carbon steel or alloy steel.
  • Corrosion-resistant double flex chain: Corrosion-resistant double flex chain is made from materials that are resistant to corrosion, such as stainless steel or plastic. It is ideal for use in applications where the chain will be exposed to corrosive elements, such as chemicals or saltwater.
  • Self-lubricating double flex chain: Self-lubricating double flex chain has built-in lubricant that keeps the chain running smoothly and reduces wear and tear. This type of chain is ideal for applications where it is difficult or inconvenient to lubricate the chain regularly.
