GR3-22D-A Compact Wire Rope Isolator
The HOAN GR3-22D-A Wire Rope Isolator is developed for lightweight electronic assemblies that require dependable protection from continuous vibration, sudden shock, and repeated movement. Its compact metal structure combines precision-machined mounting blocks with stainless steel wire rope loops, providing both flexibility and energy dissipation within a limited installation space.
Designed for photography systems, aerial surveying payloads, airborne communication units, and compact measuring devices, the GR3-22D-A helps reduce vibration transferred to sensitive components without adding unnecessary weight to the equipment.
Unlike conventional rubber mounts, this Composite wire rope isolator does not depend on elastomer elasticity. This makes it suitable for applications exposed to temperature variation, moisture, oil, ultraviolet radiation, and long-term outdoor operation.
Key Features
Compact and Lightweight Construction
The GR3-22D-A has been designed for installations where space and payload weight are limited. Its small mounting blocks and efficient cable arrangement make it easier to integrate into cameras, sensors, communication modules, and airborne electronic equipment.
Multi-Axis Vibration Protection
The curved wire rope loops can deform in compression, tension, shear, and roll directions. This allows the isolator to protect equipment from vibration arriving from more than one direction.
Effective Shock Energy Absorption
During an impact event, the stainless steel cables deform progressively rather than transferring the full shock directly to the mounted component. This helps protect circuit boards, optical assemblies, connectors, and precision mechanical parts.
All-Metal, Non-Aging Structure
The GR3-22D-A contains no rubber damping element. It is not affected by common rubber-related problems such as hardening, cracking, softening, or loss of elasticity after prolonged environmental exposure.

Product Advantages
Reduced Vibration Transmission
The cable loops introduce flexibility between the equipment and its supporting structure, helping lower the vibration energy reaching sensitive electronics and optical components.
Improved Image and Measurement Stability
For cameras, surveying sensors, and electro-optical equipment, excessive vibration can cause image blur, unstable tracking, or inaccurate data. The GR3-22D-A helps create a more stable operating platform.
Reliable Performance Across Changing Conditions
The all-metal structure maintains its function under temperature changes, moisture, dust, oil contamination, and ultraviolet exposure. It is well suited to equipment operating outdoors or on mobile platforms.
Low Installation Burden
Its compact structure allows engineers to introduce vibration isolation without significantly increasing the equipment envelope or overall system mass.
