JGX-0400D-31.5A Balanced-Load Wire Rope Isolator
Product Overview
The JGX-0400D-31.5A uses multiple stainless steel cable loops retained between two metal mounting bars.
When vibration or shock reaches the mounting structure, the wire rope bends, compresses, and moves internally. Friction between the individual wire strands contributes to energy dissipation while the cable loops provide the flexibility needed to reduce direct mechanical transmission to the protected equipment.
This working principle allows the isolator to handle vibration and transient shock without depending on a conventional rubber element.
With a height of only 33 mm and width of 43 mm, the JGX-0400D-31.5A provides a useful combination of compact dimensions and moderate mechanical compliance.
It is therefore positioned between the higher-stiffness 37A and the softer JGX-0400 models, giving engineers another option when neither maximum rigidity nor large displacement is desirable.
How the Isolation Structure Works
•A wire rope isolation system behaves differently from a simple coil spring.
•During movement, the stainless steel cable loops flex while individual strands interact internally. The combination of elastic cable deformation and friction between strands contributes to both flexibility and mechanical energy dissipation.
•Under continuous vibration, the structure helps reduce the amount of vibration transferred between the base and supported equipment.
•During a sudden impact, the cable loops deform progressively rather than behaving as a rigid connection.
•This combination is why Shock and vibration isolators based on wire rope are frequently considered for equipment that must deal with more than one type of mechanical disturbance.

Wire Rope Isolator vs. Conventional Vibration Mount
The most appropriate isolation technology depends on the actual operating conditions.
A conventional rubber mount can be a practical choice for many controlled environments and steady vibration conditions.
A wire rope isolator, by comparison, uses metallic cable deformation and internal strand friction. This makes the operating principle particularly useful when designers need an all-metal component capable of addressing vibration and mechanical shock within the same mounting system.
For this reason, wire rope insulators—more accurately referred to as wire rope isolators—are used in equipment designs where durability, mechanical flexibility, and shock response are considered together.
