GR1-1.8D-A Wire Rope Vibration Isolator for UAV Gimbals, EO/IR Cameras & Lightweight Payloads
- The GR1-1.8D-A miniature wire rope vibration isolator is specifically designed to reduce airborne vibration and impact transmitted to lightweight payload systems. Featuring a compact stainless steel cable structure and precision aluminum mounting bars, this isolator effectively protects UAV cameras, electro-optical sensors, infrared imaging devices and precision electronic payloads from continuous vibration and transient shock.
- With a maximum static load of 1.8 N, lightweight construction of only 0.05 kg, and six standard mounting configurations, the GR1 Series provides engineers with an easy-to-integrate vibration isolation solution for modern aerial platforms and compact electronic equipment.
- Compared with elastomer isolators, the wire rope design maintains stable isolation characteristics throughout its service life without hardening, cracking or performance degradation caused by environmental exposure.
Typical UAV Applications
The compact dimensions and lightweight construction make the GR1 Series suitable for a wide variety of airborne systems.

Reliable Performance in Dynamic Environments
Aircraft vibration consists of multiple excitation frequencies generated by motors, propellers and aerodynamic turbulence.
The GR1 miniature wire rope isolator helps minimize these disturbances by:
•Reducing structural resonance•
•Improving image stability
•Protecting electronic assemblies
•Increasing sensor accuracy
•Extending equipment service life
This contributes to higher mission reliability and improved data quality.
