Introduction
In the field of vibration control for industrial equipment and precision instruments, rubber isolators have become the mainstream choice due to their excellent performance and economy. However, there are a wide variety of products on the market, and how to choose the appropriate rubber isolator and use it correctly for maintenance is a concern for many users. This article will comprehensively analyze the selection principles, product introduction, installation and maintenance, etc., to help users make wise choices.
Core selection elements of rubber isolators
Load matching is the primary principle
The first step in choosing a rubber isolator is to accurately calculate the equipment load. Divide the total weight of the equipment by the number of support points to obtain the single point load. The load coverage range of LeadTop's POT-P series solid rubber isolators is 180-800kg/piece, which can meet various needs from light instruments to heavy equipment.
When selecting, it is recommended to reserve a 20% safety margin to avoid prolonged exposure to extreme load conditions. For example, a 600kg equipment uses 4-point support and a single point load of 150kg. It is recommended to choose a vibration isolator with a rated load of about 200kg, which can ensure the vibration isolation effect and extend the service life.

Frequency characteristics determine the isolation effect
Understanding the sensitive frequency of the equipment and the environmental vibration frequency is the key to selection. The vertical natural frequency of rubber isolators is 6.5-12Hz, and the horizontal natural frequency is 3-8Hz. When the environmental vibration frequency is higher than three times the natural frequency, the isolation efficiency can reach over 90%.
For equipment sensitive to low-frequency vibrations, such as atomic force microscopes, laser interferometers, etc., models with lower natural frequencies should be selected. For scenarios dominated by mid to high frequency vibrations, products like the POT-P series are very suitable.
Environmental conditions affect product selection
The selection of rubber isolators is directly affected by factors such as temperature, humidity, and corrosiveness in the usage environment. The standard rubber material is suitable for temperatures ranging from -20 ℃ to+70 ℃, and special formulations can be extended to -40 ℃ to+100 ℃.
In corrosive environments, isolators with protective coatings should be selected. Clean room environments require the selection of dust-free and non shedding products. For outdoor use, special requirements such as UV protection and anti-aging should be considered.

Product Technical Features
The POT-P series rubber isolators adopt composite rubber damping technology and achieve excellent vibration energy dissipation capability through specially formulated rubber materials. The product adopts a combination rubber structure design, which has strong integrity, is not easily deformed, and has a stable and reliable structure.
Technical performance indicators: vertical natural frequency 6.5-12Hz, horizontal natural frequency 3-8Hz, damping ratio 0.05-0.2, load coverage 180-800kg/piece, recovery time less than 5 seconds. These parameters ensure that the product can effectively isolate mid to high frequency vibrations, meeting the needs of most industrial and scientific research scenarios.
Structural design advantages
The rubber isolator is equipped with a lifting adjustment seat, which can achieve a height adjustment range of ± 10mm and a leveling accuracy of ± 0.1mm. This design makes the installation process simple and fast, and users can accurately level according to their actual needs to ensure that the equipment is in the best working condition.
The product can be equipped with casters for easy device movement and position adjustment. For devices that require frequent movement, this configuration greatly improves the flexibility of use. When fixed installation, a fixed base can be chosen to enhance stability.
Widely applicable in various fields
The POT-P series rubber isolators are suitable for fields with low vibration requirements such as microscopes and medical biology. Specific applications include: optical microscope systems, biochemical analyzers, coordinate measuring machines, laser processing equipment, precision testing instruments, etc.
In the field of intermediate frequency isolation, this product performs particularly well. Compared to air floating isolators, it does not require complex air circuit systems, has lower maintenance costs, and is suitable for long-term stable operation.
Key points of installation technology for rubber isolators
Basic surface treatment
Before installing the rubber isolator, it is necessary to ensure that the surface flatness of the foundation reaches 0.05mm/m~0.1mm/m. An uneven foundation can lead to uneven stress on the isolator, affecting the isolation effect and accelerating wear.
If necessary, use leveling mortar or steel plates for foundation treatment. Clean the installation area to ensure there are no debris or oil stains, creating favorable conditions for installation.
Horizontal leveling operation
The key step in installation is to use the lifting and adjusting seat for precise leveling. The leveling accuracy should reach ± 0.1mm and be tested using a precision level. During the leveling process, uniform force should be applied to avoid single point overload.
After leveling is completed, lock the adjustment seat to prevent loosening during use. For equipment with multi-point support, it should be ensured that each support point is evenly stressed.
Connection fixing method
Select the appropriate connection method based on the characteristics of the device. For equipment with high vibration, it is recommended to use bolt fixation to enhance connection stability. For devices that need to be moved, optional casters are available for easy position adjustment.
Rubber isolators should be equipped with anti slip pads between the equipment and foundation to prevent sliding displacement. The connecting bolts should be checked and tightened regularly to ensure long-term stability.
Daily maintenance of rubber isolators
Regular inspection system
Establish a regular inspection system for rubber isolators, and it is recommended to conduct a comprehensive inspection once every quarter. The inspection includes: whether there are cracks and aging phenomena on the rubber surface; Is the adjustment seat loose; Has the load changed.
Discover problems and handle them promptly to avoid affecting the isolation effect. If there are obvious cracks or aging on the rubber surface, a new isolator should be replaced in a timely manner.
Cleaning and Protection
Keep the surface of the rubber isolator clean and avoid contact with oil and chemicals. Long term exposure to oil stains on rubber materials can accelerate aging and reduce their elasticity.
Use neutral cleaning agents and soft cloths during cleaning, and prohibit the use of organic solvents. When used in harsh environments, it may be considered to install protective covers to extend their service life.
Performance testing verification
Conduct an annual vibration isolation performance test to verify whether the isolation effect of the rubber isolator has decreased. A vibration tester can be used to measure the vibration value of the equipment during operation and compare it with the data during installation.
If the isolation efficiency decreases by more than 20%, replacement of the isolator should be considered. Generally speaking, the service life of rubber isolators is 5-10 years, depending on the usage environment and maintenance conditions.
Conclusion
The correct selection, installation, and maintenance of rubber isolators are key to ensuring their long-term stable operation. Following scientific selection principles, strictly implementing installation specifications, and establishing a regular maintenance system can fully leverage the performance advantages of rubber isolators.
