Cushioned Aluminum Base Rubber Spring Isolator 25mm Anti Vibration Spring Mount
Product Details
Aluminum Base Rubber Spring Isolator
,25mm Cushioned Anti Vibration Spring Mount
,Resonant Fatigue Vibration Isolation Spring Mount
The JD Series Spring Vibration Isolator is engineered for HVAC air conditioners, fans, and pumps, delivering a rated load deflection of 25 mm. Built to tame vibration at the source, the isolator absorbs dynamic energy before it reaches the frame or slab, reducing re-radiated noise and the risk of resonant fatigue.
Uniform loading through the spring base prevents premature fatigue of the assembly.
Low natural frequency keeps the spring well below the disturbing frequency of the equipment.
Anti-corrosion coating and a durable rubber base keep the unit reliable indoors and out.
Suits water pumps, fans, air-handling units, chillers, and general industrial machinery.
- Lightweight yet rigid frame that installs quickly on any equipment base.
- Every spring is heat-treated, electrophoretically coated, and baked for lasting rust resistance.
- Rated deflection of 25 mm cuts structural vibration at the source.
- Baked varnish on the spring surface gives excellent anti-corrosion performance.
- 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.
