GR1-3.3D-A Miniature Wire Rope Vibration Isolator for Precision Electronics & UAV Systems
Product Detail Description
1. 3.3kg Heavy-Duty Load Capacity · Professional-Grade Support
The GR1-3.3D-A offers a maximum static load capacity of 3.3kg, recommended for equipment in the 2.0–3.5kg range. Ideal applications include:
Cinema-grade 3-axis gimbals + full-frame mirrorless cameras
Professional gyro-stabilized gimbals + broadcast cameras
Heavy-lift drone multispectral sensor arrays
Helicopter external camera systems
2. Non-Linear Damping · Full-Spectrum Vibration Isolation
The wire rope strand friction mechanism provides broadband vibration suppression:
High frequency (>200Hz): Effective isolation of motor and propeller vibrations
Mid frequency (20–200Hz): Significant attenuation of structural resonance
Low frequency (<20Hz): Control of flight attitude oscillations
Resonance magnification factor: ≤4 (superior to rubber isolators' typical 6–10x)
3. Controlled Buckling · Impact Protection
In the event of hard landing or emergency descent, the wire rope's controlled buckling mechanism allows the gimbal to buffer within its travel range, absorbing impact energy and protecting the precision camera and gimbal motors from damage.
4. All-Metal Construction · 5-Year Service Life
Stainless steel wire rope + aluminum or stainless steel mounting plates completely eliminate rubber aging, creep, outgassing, and ozone degradation. Under typical operating conditions, product lifespan exceeds 5 years, achieving true maintenance-free operation after installation.
5. Extreme Environmental Adaptability
Operating temperature: -55°C ~ +200°C
Salt spray resistance: Suitable for marine operations
Oil and fuel resistance: Can contact fuels and lubricating oils
UV resistance: Performance unchanged after prolonged outdoor exposure
