Round Spring Vibration Isolator and Spring Shock Absorber for Floor Mounted Vibration Attenuation
Product Details
25 mm Load Deflection
,Corrosion-Resistant ED Finish
,Low-Frequency Spring Isolator
The JD Spring Vibration Isolator is engineered for HVAC air conditioner fans, pumps, and similar equipment, providing a load deflection of 25 mm. Where structure-borne noise and fatigue are a concern, the isolator absorbs dynamic energy before it reaches the frame or slab—cutting structure-borne noise and protecting bearings over a long service life.
Structural balance ensures the mount carries the machine without distortion.
Tuned to sit below running speed, the spring avoids the amplification zone entirely.
Anti-corrosion coating and a durable rubber base keep the unit reliable indoors and out.
Widely used with fans, pumps, generating sets, and process equipment of many sizes.
- Anti-rust finish tested to ASTM B-117 and CNS 8886 salt-spray standards
- Stress-relieved springs deliver outstanding fatigue resistance under cyclic load
- Weather-resistant rubber body and galvanised stamped parts resist the elements
- Flexible pedestal base fits a wide range of machinery
- Straightforward bolt-down installation saves maintenance time
- Spring diameter exceeds 0.8 times the depressed height for stable support
- Uniform load distribution across the spring cage reduces wear
- Low natural frequency keeps the unit clear of the operating range
- Adjustable height option lets you fine-tune level after installation
- Compact footprint suits tight mechanical rooms
