The 4 Types of Flex Cable

When choosing cable for a flex application, it is crucial to consider the specific type of flexing your cable will endure. This consideration is key to finding a cable that not only performs effectively but also lasts. Selecting the wrong type of cable can lead to rapid deterioration of the jacket and insulation, resulting in costly product replacements, increased downtime, and the need for a second installation. At Allied Wire & Cable, we offer a wide variety of wire flex types designed to meet the demands of different applications. Our expert team is ready to help you choose the best option for your next project, ensuring long-lasting performance and reliability.

There are four types of flex cable. We will go through them, so you can find the perfect flexing cable for your application’s needs the first time around.

Torsional Flex

Torsional flex cables are engineered to handle twisting motions, typically around an axis. This type of flexing is common in robotic pick-and-place equipment, industrial automation, and machinery with rotating parts, such as robotic arms and wind turbines. These cables are designed to endure repeated twisting without compromising their performance, making them ideal for dynamic applications where rotational movement is essential.

Rolling Flex

Rolling flex cables are pulled through cable tracks or pulley systems, often facing continuous and repetitive movement. These cables are commonly used in automated manufacturing systems, conveyor belts, and material handling equipment. Due to the nature of their application, rolling flex cables must be highly abrasion-resistant and durable to withstand constant flexing without wear and tear.

Bending Flex (Tic-Toc Flex)

Bending flex, also known as Tic-Toc Flex, involves cables that bend repeatedly in a back-and-forth motion. These cables are commonly found in applications such as door controls, lifting equipment, and anywhere a cable must endure frequent lateral movements. Cables used in these situations need to have robust insulation and jackets to withstand the mechanical stress of repetitive bending.

Variable Flex (Random Flex)

Variable flex cables are designed for applications where the cable moves freely in various directions, often in a random or unpredictable manner. This type of flexing is typical in robotic systems, automated machinery, and medical devices where the cable must adapt to complex and varied movements. These cables are built with flexibility and resilience to accommodate the dynamic and variable motions they experience.

Now that you can identify the four different types of flex, you are well on your way to finding an appropriate cable solution for your flexing application!
