Vibrostop Cavoflex

The Vibrostop Cavoflex range is a development of the original helically wound wire rope shock mounts developed in the USA in the 1950's and which have expanded from their original military uses to satisfy numerous additional industrial applications including of course modern NATO and MIL specifications.

The design provides for vibration isolation for small amplitude forcing frequencies but is most commonly used as a shock mount where it excels due to its very high capacity for predictable deflection under shock loads.

A wide range of load conditions can be accommodated by virtue of the variable parameters inherent within the mounting.  The principal variables are of course the wire diameter and spacing of the mounting bars.  The design also allows for different orientations of the mounting to satisfy attachment requirements due to its near isotropic performance.

The range covers standard wire sizes from 1.5 to 22.0mm and optionally up to 39mm diameter on request..  By providing height and width variables a wide range of requirements can be satisfied from the standard range.   Specials to suit specific requirements may also be available.

As standard the wire rope is a specially selected stainless steel grade and the mounting bars are made from an aluminium alloy with an Alodine® 1200  protective finish. (chemical conversion protective coating)

The bars can also be provided in stainless steel as an additional cost option.

Mounting orientations typically used are illustrated below from left to right these are:

• Fixed roll
• 45deg roll/shear
• Plain compression
• Fixed shear

Multiples can be used to provide lateral stability or to increase static and shock load capacity.

Models and Dimensions – Cavoflex

The smaller mounts have a 2 hole fixing for the top and bottom mounting bars.  These are countersunk to suit the appropriate mounting bolt or screw type.  Optionally a counter bore or  Wire thread inserts such as Helicoil^TM can also be provided.

Table– 2 Mounting Holes

The Part number code provides the basic dimensions for the mount. The four groups of numbers signify the wire diameter, overall length, height and width. For example, H25.112.28.33 represents a mount with 2.5 mm wire thickness, a length of 112 mm and height and width of 28mm and 33mm respectively.
