JGX-0400D-17.5A Soft-Response Wire Rope Isolator
The JGX-0400D-17.5A wire rope isolator is the most compliant model in the JGX-0400 Series, developed for equipment that requires greater mechanical movement and a softer mounting response.
In the primary loading direction, the model provides a 17.5 kg maximum static load, 32.0 mm maximum deflection, and 58 kN/m vibration stiffness. This combination gives it the lowest vibration stiffness and greatest primary-direction deflection among the five JGX-0400 models.
Rather than holding the supported equipment through a relatively rigid interface, the stainless steel cable loops provide controlled flexibility between the equipment and its mounting structure. This makes the 17.5A particularly relevant when vibration isolation performance and available movement are more important than maximizing load capacity.
Its all-metal cable construction also enables the same wire rope mount to respond to both recurring vibration and transient mechanical shock without relying on a conventional rubber spring element.
Key Product Features
•58 kN/m Low Vibration Stiffness:The JGX-0400D-17.5A has the lowest primary-direction vibration stiffness in the JGX-0400 Series.Its 58 kN/m Kv value makes it particularly relevant when a softer mechanical connection is required between equipment and the vibration source.
•32 mm Primary Deflection:Maximum primary-direction deflection reaches 32.0 mm, providing significantly more available movement than the higher-load JGX-0400 variants.
•44.7 mm Deflection at 45°:Under the specified 45° loading condition, available displacement reaches 44.7 mm.This highlights the highly compliant behavior of the 17.5A and also makes installation clearance an important design consideration.
•All-Metal Flexible Structure:The flexible element consists of stainless steel wire rope rather than a rubber spring.Cable bending and internal strand interaction create the mechanical response required for vibration and shock management.

Why a Softer Wire Rope Mount Matters
A vibration isolation system is not improved simply by selecting the stiffest available mount.
When the mounting interface is too stiff, more dynamic input may be transmitted directly from the supporting structure into the protected equipment.
The JGX-0400D-17.5A approaches the problem differently.
Its stainless steel wire rope loops provide a more compliant mechanical path. As the base moves, the cable structure can flex, allowing relative movement between the source and the protected assembly.
This is particularly useful when equipment mass, excitation frequency and available installation space support the use of a lower-stiffness isolator.
However, softer is not automatically better.
The increased movement associated with the 17.5A means engineers must verify that sufficient clearance exists and that the supported equipment will not contact surrounding structures during operation or shock events.
Mechanical Energy Management Through Wire Rope
The JGX-0400D-17.5A does not behave like a simple metal coil spring.
When the isolator is displaced, the individual strands within the stainless steel wire rope interact as the cable bends. This produces internal friction while the overall cable geometry supplies restoring force.
The resulting behavior combines:
Flexible cable deformation for controlled relative movement,with
Inter-strand friction for mechanical energy dissipation.
This is the operating principle behind many Stainless steel wire rope isolators used for combined vibration and shock protection.
Because both functions are integrated into the cable structure, these products fall into the broader category of Shock and vibration isolators.
