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.
