JGX-0400D-22A Flexible-Response Wire Rope Isolator
Product Overview
The JGX-0400D-22A is positioned toward the more compliant end of the JGX-0400 family.
Its primary-direction vibration stiffness is 84 N/mm, considerably lower than the 116 N/mm of the JGX-0400D-26A. At the same time, maximum deflection increases from 19.8 mm to 24.9 mm.
This combination allows the cable loops to undergo greater controlled deformation before reaching the published displacement limit.
Instead of relying on an elastomer as the flexible element, the isolator uses stainless steel cable. As the wire rope bends under dynamic input, strand interaction and cable deformation contribute to the mechanical response of the mounting system.
For engineers, the 22A provides another option when a higher-stiffness wire rope isolator would restrict movement more than the application requires.
Lower Stiffness for Greater Mechanical Compliance
The main engineering characteristic of the JGX-0400D-22A is not simply its 22 kg load rating.
Its more important distinction is its 84 N/mm vibration stiffness combined with 24.9 mm maximum primary-direction deflection.
A lower-stiffness mounting interface allows greater relative movement between the supported equipment and its base. This can be useful where a rigid or high-stiffness connection would transmit too much mechanical input into the protected assembly.
The effect becomes even more apparent at 45° loading, where the published maximum deflection reaches 35.6 mm.
For applications where adequate clearance is available, this increased travel gives engineers more freedom when designing a compliant isolation system.

Shock and Vibration Response
Continuous vibration and sudden mechanical shock impose different demands on a mounting system.
During vibration, the cable loops repeatedly flex as the supporting structure moves. During transient loading, larger deformation of the rope structure can help accommodate relative movement and dissipate part of the mechanical energy.
This combined behavior allows wire rope products to function as Shock and vibration isolators rather than serving only as simple vibration mounts.
For the JGX-0400D-22A, the published primary-direction values are:
Kv (Vibration): 84 KN/m
Ks (Shock): 37 KN/m
These values should be considered together with the equipment mass, input frequency, mounting configuration and required travel.
All-Metal Isolation Without a Rubber Spring
One reason engineers consider a wire rope mount is its fundamentally different construction from a conventional elastomeric vibration mount.
The JGX-0400D-22A uses stainless steel cable as its primary flexible element.
During displacement, the cable loops bend while the strands within the rope interact. This creates a combination of elastic response and internal friction.
There is no rubber element providing the primary spring action.
This makes Stainless steel wire rope isolators an alternative for equipment designs where an all-metal isolation mechanism is preferred or where vibration and shock must be addressed using the same mounting component.
