chainflex® cables with small bending radii ideal for tight installation spaces

Cables with a tight bending radius for a range of dynamic applications

Traditional cables with copper conductors quickly reach their mechanical limit in applications with tight bending radii. chainflex® cables, however, are engineered with a bending-resistant design and excellent mechanical properties.

The bending radius is usually expressed as a multiple of the outer diameter of the cable. Sometimes this is already calculated specifically for your cable and is then expressed as a value in mm. Learn how to apply bending radius correctly.

The sheath materials of chainflex® are highly flexible and abrasion-resistant, providing a guaranteed extended service life for a high number of strokes and the smallest bending radii. Learn more about the advantages of chainflex® cables here.

All chainflex® cables are rigorously tested in our 41,000 sq. ft. test lab in Cologne, Germany to guarantee 2 billion test cycles per year.
UL-verified with up to 4 year guarantee
Extended service life
Available from stock in any quantity with no minimum length requirement

How to apply a bending radius correctly?

If you bend a cable too far, this considerably shortens the lifespan of your cable. On the outside of the bend if you have 'stretched out' the cable materials, they become thinner or perhaps even show cracks - as a result of which the original electrical properties of the conductor insulation are lost.

So, how do you do it safely?

What is the bending radius of a cable?

The bending radius expresses the smallest possible bend with which one can safely bend a cable without kinking it, damaging it or shortening its life span. The smaller the bending radius, the shorter bends you can make.

The bending radius is typically expressed as a multiple of the outer diameter of the cable, for example: 4xD or 12xD where "D" is the outer diameter of the cable. Chainflex cables are calculated specifically and expressed as a value in mm. Bending radii vary according to the type of cable and the section. The bending radius that applies to a cable is stated in its technical data sheet.

How to correctly apply the bending radius?

The cable should be bent around an imaginary circle whose radius is at least the bending radius of your cable. The bend radii is measured at the inner curvature of the cable.
