What Is A Double Flex Fhain?

Double Flex Chain is a type of conveyor chain that consists of two parallel chains connected by crossbars or links. It is designed to provide flexibility and enable smooth movement around curves and bends in conveyor systems. The crossbars or links between the two chains allow the chain to flex and accommodate changes in direction, making it suitable for applications where straight-line conveyors are not feasible or efficient.

The construction of Double Flex Chain typically includes outer sidebars, inner sidebars, crossbars, and pins. The outer sidebars and inner sidebars run parallel to each other, with the crossbars connecting them at regular intervals. The pins secure the crossbars and sidebars together, allowing the chain to articulate and bend.

How To Maintain The Double Flex Fhain?

Here are some maintenance tips to consider:

Regular Inspection: Conduct periodic visual inspections of the double flex chain to check for any signs of wear, damage, or misalignment.

Lubrication: Proper lubrication is crucial for the smooth operation and longevity of the double flex chain.

Cleaning: Keep the double flex chain clean and free from dirt, debris, and contaminants.

Tension Adjustment: Maintain proper tension in the double flex chain to prevent excessive wear and elongation.

Sprocket Inspection: Inspect the sprockets that interact with the double flex chain. Check for signs of wear, damage, or misalignment.

Double Flex Chain Advantage



As the name suggests, double flex chains are highly flexible. They can accommodate angular misalignment, making them ideal for applications that involve curved paths, bends, or changes in direction.

Misalignment Compensation

Double flex chains can compensate for small angular misalignments between the driving and driven shafts.

Smooth Operation

Double flex chains provide smooth and quiet operation. The flexibility of the chain reduces vibration and noise, contributing to a quieter and more comfortable working environment.

High Load Capacity

Double flex chains are designed to handle significant loads. They are constructed with high-strength materials, ensuring reliable power transmission even in demanding applications.

Application of Double Flex Chain


What is the working principle of Double Flex Chain?

The working principle of a double flex chain can be summarized as follows:

The driving sprocket rotates, imparting motion to the chain.
The chain links engage with the sprocket teeth, creating a positive drive.
The flexible nature of the chain allows it to accommodate angular misalignment between the driving and driven shafts.
As the chain moves, the pins and bushings rotate, transmitting power from the driving to the driven shaft.
The chain continues to engage with the sprocket teeth, maintaining the transfer of power and guiding the chain’s movement.
