Technical details and manufacturing context for Vibration Isolators
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Rated Load Capacity | 50–5000 kg | Per isolator; select based on equipment weight and dynamic load. |
| Natural Frequency | 5–15 Hz | Lower frequency provides better isolation but requires softer elastomer. |
| Transmissibility | ≤0.1 | At resonance; lower is better for isolation efficiency. |
| Damping Ratio | 0.05–0.20 | Higher damping reduces resonance amplification but may reduce high-frequency isolation. |
| Maximum Static Deflection | 10–50 mm | Under rated load; affects natural frequency. |
| Operating Temperature Range | -40–85 °C | Elastomer performance degrades outside this range. |
| Elastomer Hardness | 40–70 Shore A | Affects stiffness and damping.ISO 7619-1 |
| Elastomer Material | NR, CR, NBR, EPDM | Select based on chemical and temperature resistance.ISO 1629 |
| Housing Material | Steel, Stainless Steel, Aluminum | Corrosion resistance and strength. |
| Dimensions (L×W×H) | 100×100×50 – 600×600×200 mm | Varies with load capacity; ensure mounting space. |
| Weight | 1–50 kg | Per isolator; affects handling and installation. |
| Mounting Hole Diameter | 8–20 mm | For bolt size; ensure compatibility with mounting hardware. |

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The rated load capacity per isolator is typically between 50 and 5000 kg, depending on the model. Selection should be based on the equipment weight and dynamic load. Always verify the specific capacity with the manufacturer.
Lower natural frequencies provide better isolation but require softer elastomers. The typical range is 5–15 Hz. The isolator should be selected so that the natural frequency is well below the excitation frequency to achieve effective attenuation.
Transmissibility is the ratio of transmitted force to input force. At resonance, it should be ≤0.1 for good isolation efficiency. Lower values indicate better vibration reduction. Verify the transmissibility for your specific application.
Regularly inspect isolators for wear, cracking, or permanent set. Check that mounting bolts are tight and that the isolator is not overloaded. Replace isolators if they show signs of degradation to prevent increased vibration transmission.
