GR2-9.3D-A Compact Wire Rope Isolator
The GR2-9.3D-A Wire Rope Isolator is a miniature all-metal isolation component developed for sensitive equipment that must remain stable under continuous vibration, sudden impact and repeated movement.
With a height of only 19 mm, an approximate weight of 0.06 kg and a compact 21 mm-wide structure, it is particularly suitable for systems where installation space and payload weight are strictly limited. Typical examples include professional imaging equipment, aerial surveying payloads, airborne communication modules and compact precision instruments.
The isolator uses Φ3.3 mm stainless steel wire rope as its elastic and damping element. When external vibration or shock acts on the equipment, relative movement between the individual wire strands creates frictional damping, helping reduce transmitted energy without using rubber or liquid damping materials.
Key Features
Small Footprint for Space-Constrained Assemblies
The compact 19 mm structure allows the GR2-9.3D-A to be installed inside small camera platforms, UAV payload modules and lightweight communication enclosures.
Low-Weight All-Metal Construction
At approximately 0.06 kg per unit, the isolator adds minimal weight to airborne and portable systems while providing mechanical protection for sensitive components.
Combined Shock and Vibration Control
The stainless steel cable loops provide elastic support while friction between the strands dissipates energy. The product can therefore function as both a Wire Rope Vibration Damper and a Wire Rope Shock Absorber.
Multidirectional Flexibility
The cable structure can respond to compression, shear and combined loading. This makes it suitable for equipment exposed to vibration from several directions rather than from only one fixed axis.
Resistant to Repeated Impact
The all-metal structure is designed for applications involving frequent take-off, landing, transportation shock and platform movement, where repeated loading may shorten the life of ordinary rubber mounts.
Multiple Installation Options
A, B, C, D, E and S mounting configurations provide greater freedom when designing compact equipment brackets and internal support structures.

Product Advantages
Improved Protection for Sensitive Payloads
The GR2-9.3D-A helps reduce the vibration and shock energy reaching cameras, sensors, circuit boards and communication components, lowering the risk of loose connections, image instability and mechanical fatigue.
Suitable for Harsh Service Conditions
Because it contains no rubber damping element, the Cable Isolator is suitable for environments involving temperature variation, moisture, UV exposure, oils and other conditions that may accelerate elastomer aging.
Stable Performance Over a Long Service Period
Stainless steel wire rope provides high fatigue resistance under repeated deformation. The isolator does not suffer from the cracking, hardening or permanent aging commonly associated with conventional rubber components.
Simplified Maintenance
The passive all-metal structure requires no power supply, lubrication or routine replacement of damping media, making it suitable for equipment that is difficult to access after installation.
Flexible Model Selection
The GR2 family includes several sizes and load ranges. Engineers can select an appropriate model according to equipment mass, mounting arrangement and required displacement rather than redesigning the complete support structure.
