Motion Types of Metal Hose Assembly

Most industrial applications can be reduced to one of five classes of motion: Angular, Axial, Offset, Radial; or Random

Angular
Motion that occurs when one end of a hose assembly is deflected in a simple bend with the ends not remaining parallel. Angular motion may be incorporated in an installation to accommodate misalignment and vibration only, but must not be used to accommodate expansion that would result in unloading the braid.
Axial
This type of motion occurs when one end of a hose assembly is deflected along its longitudinal axis. Axial motion is applicable to annular corrugated, unbraided flexible hose only. Neither helical hose nor braided hose should be used in axial motion applications.
Offset
Motion that occurs when one end of the hose assembly is deflected in a plane perpendicular to the longitudinal axis with the end remaining parallel. Offset is measured in inches of displacement of the free end centerline from the fixed end centerline. In offset motion applications, the offset should never be greater than one fourth (25%) of the minimum centerline bend radius
Radial
This type of motion occurs when the centerline of a hose assembly is bent in a circular arc. In industrial applications, radial motion is most commonly found in traveling loops.
Random
Non-predictable motion that occurs from manual handling of a assembly. Loading and unloading hose would generally fall into this category. Abusive handling of hose is an important factor to consider in applications involving random motions. The use of an interlocked (RT-6) guard over the corrugated hose is recommended to protect the hose assembly from rough handling and "over-bending" adjacent to the fittings.
