Spring Isolator VT4414 – VT4424
All-metal isolator with a natural frequency of 3 – 4 Hz. Isolator with steel spring, damping element in 18/8 stainless steel wire and scrolls in aluminium.
Product Characteristics
Very soft isolators designed for loading in compression only.
Weights for VT4414 (depending on suffix): 0.15 – 0.28 kg
Weights for VT4424 (depending on suffix): 1.20 – 1.50 kg
Maximum excitation amplitude: ± 1 mm.
Mechanical strength: 2 g
Natural frequency: 3 – 4 Hz
Amplification factor Q: < 8
Temperature range: -90° to +300° C.
Product Applications
Isolation of low speed rotating machines such as fans, compressors, generating sets, engines, and protection of sensitive equipment from vibrations.
Note
The isolators are delivered without mounting plate, which can be ordered separately. For greater static loads, multiple spring isolators are mounted together as a package (consult us).
