There are four common types of flexing to consider when designing and applying a flexing cable.
They are Rolling Flex, Bending or “Tick-Tock” Flex, Torsional Flex and Variable/Random Flex.
ROLLING FLEX
Rolling Flex Applications include linear motion associated with cable
track systems or single axis slide apparatus. (See figure 1.) The most
common type of rolling flex includes cable track systems where the
cables are “managed” within an enclosed rolling motion carrier.
Figure 1
BENDING FLEX
Bending or “Tick Tock” Flex occurs when a cable is subjected to
repetitive motion at a fixed point in the axis of the cable. The bending
moment of the cable is subjected to stress and fatigue from lateral
motion in these applications.

BENDING FLEX
TORSIONAL FLEX
Torsional Flexing Applications occur when the cable is subjected to
twisting forces, usually in a circular motion around the central axis of
the cable. Robotic and pick/place apparatus are the most common
applications subjecting cables to torsional stress.

VARIABLE FLEX
TORSIONAL FLEX
Variable Flexing Applications are random applications, which may
occur in any number of flexing environments. Examples include articulation
found in robotics, automated equipment and hand-held devices.

Alpha Wire Company offers a line of high flex XTRA •GUARD ® Flexible Cable products designed specifically for each of the four listed
types of flexure. In addition, Alpha’s Engineering Staff can assist the user in the design of application specific cables to suit specific needs, or in
the specification of an existing Alpha Wire product. A close examination of the flex requirements and the physical, mechanical or environmental
requirements is an important first step in the determination of product selection. A product design specification worksheet can be found on page
405 of this Master Catalog to assist you in the selection process.
