GR2 Series
Precision Protection, Born from Innovation: Hong'an Microwave GR Series Wire Rope Isolators
In the field of vibration and shock control, the GR series wire rope isolators from Xi'an Hoan Microwave Co., Ltd. provide crucial protection for various precision instruments and equipment with their unique design concept and excellent performance. This isolator, vividly called "butterfly-shaped", is not only named for its elegant appearance, but more importantly, it achieves efficient energy dissipation through its delicate structural mechanical properties similar to butterfly wings.
The core secret of the GR series lies in its elaborately braided spiral stainless steel wire rope structure. Countless strands of high-strength steel wires are wound at specific angles to form a nonlinear damping system. When vibration or shock occurs, tiny friction and slippage take place between the layers of the wire rope, just like numerous small "spring-damper units" working together, efficiently converting destructive mechanical energy into heat energy for dissipation. This unique "dry friction" damping mechanism endows the GR series with excellent broadband vibration isolation capability, especially in suppressing medium-high frequency vibrations and transient shocks.
Compared with traditional rubber or metal spring isolators, Hoan Microwave's GR series excels in load-bearing capacity, fatigue resistance, and environmental adaptability (resistance to high and low temperatures, oil, and corrosion). Its structure is free from aging issues, featuring a long service life and extremely low maintenance requirements, providing reliable guarantee for the long-term stable operation of equipment. Whether beside precision optical platforms, high-end medical imaging equipment, or in the precision instrument cabins of vehicles and ships, this "metal butterfly" silently fulfills its duty of guarding precision, which is a vivid embodiment of Hoan Microwave's profound technical accumulation and innovative spirit.

* Material of Mounting Bars *
Stainless Steel or Aluminum can be selected
* Surface Treatment Selection of Aluminum Mounting Bars *
* White Anodizing: The surface treatment to make the aluminum surface harder than itself. The color of the white anodized aluminum mounting bars keep the same color as the aluminum itself. It is the normal surface treatment of the aluminum mounting bars;
* Hard Anodizing: The surface treatment to make the aluminum mounting bars much more harder than the white anodized way. The color of the hard anodized aluminum mounting bars is more darker than the white anodizing way. Special use for complex or special requirements of the working conditions of the using of wire rope isolators.
