Passive isolators suppress vibration transmission through mechanical structure or material properties, which is crucial for the stable operation of precision equipment. Starting from technical principles, this article analyzes the structural characteristics and application scenarios of three mainstream passive isolators.

Rubber based isolator: a high-frequency vibration killer

Taking LeadTop's hollow cone rubber isolator POT-G series as an example, it adopts high-tech rubber and hollow cone structure, and effectively isolates mid to high frequency vibrations of 10-1000Hz through dual energy dissipation of material damping and geometric deformation.

The product has a natural frequency of 4-8Hz and a load range of 50-700kg, suitable for scenarios such as microscopy and optical manufacturing. Its advantages lie in its compact structure, easy installation, equipped with optional casters and precision adjustment system, which can quickly adapt to different equipment needs.

Air floating pendulum type isolator: ultra-low frequency vibration terminator

LeadTop's ZDT-B series swing rod air floating isolator is based on the principle of a single pendulum and an ultra-thin composite airbag design, with a horizontal natural frequency as low as 1.0-1.5Hz and a vertical frequency of 1.0-2.0Hz.

By dynamically adjusting the system stiffness with an external damper, the vertical/horizontal isolation efficiency in the 5Hz frequency band reaches 86-92% and 88-94%, respectively, making it particularly suitable for devices sensitive to micro vibrations such as laser interferometers. Its automatic leveling function and silent design further enhance the user experience.

High damping air floating vibration isolator: expert in high-frequency vibration attenuation

The ZDT-Z series of high damping air floating vibration isolators adopts multi small hole quasi laminar damping technology, with a vertical natural frequency of 1.0-2.5Hz, a vibration isolation efficiency of 80-86% at 5Hz, and a recovery time of less than 2s.

 Its high damping characteristics can quickly attenuate vibration energy, and when combined with a silent pneumatic system, it becomes an ideal choice for high-precision equipment such as coordinate measuring machines. LeadTop supports flexible configuration for users based on load requirements through modular design.

The selection of passive isolators requires comprehensive consideration of frequency range, load capacity, and installation environment. LeadTop provides a one-stop solution from basic protection to high-end customization for precision manufacturing, scientific research experiments, and other fields with a full range of passive vibration isolation products.
