JGX-0400D-26A High-Deflection Wire Rope Isolator
Product Overview
The JGX-0400D-26A occupies the middle range of the JGX-0400 Series.
Instead of maximizing stiffness, this version provides additional working deflection. Its 19.8 mm maximum displacement is approximately 35% greater than the 14.7 mm available from the JGX-0400D-31.5A in the primary loading direction.
This additional movement gives the stainless steel cable loops more room to deform when mechanical input reaches the mounting system.
The result is a useful configuration for applications where a very stiff mount may transmit too much vibration, but a much softer isolator would provide insufficient equipment support.
With dimensions of approximately 38 mm high × 48 mm wide × 127 mm long, the JGX-0400D-26A maintains the compact form of the JGX-0400 family while providing increased mechanical compliance.
Engineering Advantages
•Greater Mechanical Compliance:The 19.8 mm primary-direction deflection gives designers more movement capability than the higher-load JGX-0400 models.
•Medium Stiffness Position:At 116 N/mm, the 26A provides a useful middle stiffness within the series rather than pushing the system toward either extreme.
•Vibration and Shock Response:The same cable-loop structure responds to recurring vibration and transient mechanical shock.
•Multiple Installation Configurations:Six listed mounting options increase flexibility when incorporating the isolator into an existing mechanical design.
•No Elastomeric Isolation Spring:The primary flexible element is stainless steel cable rather than rubber.

More Isolation Travel in a Compact Structure
One of the defining characteristics of the JGX-0400D-26A is its increased deflection capability.
In the primary direction, the isolator permits up to 19.8 mm of movement. At 45°, maximum deflection increases to 27.9 mm.
This additional travel gives the cable structure more room to respond to mechanical displacement before reaching its published maximum deflection.
For equipment designers, this can be valuable when the mounting system needs greater compliance than the higher-stiffness members of the JGX-0400 Series can provide.
The 26A therefore represents a transition from the relatively firm 37A and 31.5A versions toward the softer 22A and 17.5A models.
