A picture of the spring isolators VT4412

Spring Isolators VT4412 and VT4422

This is a metal isolator made with a spring in high tensile steel, resilient cushion of 18/8 stainless steel wire mesh. Excellent for vibration isolation because of is very low natural frequency.

Product Characteristics

Very soft spring isolators designed for loading in compression only. 

Schrolls: aluminium
Weights for VT4412 (depending on suffix): 0.13 – 0.21 kg
Weights for VT4422 (depending on suffix): 1.20 – 1.50 kg
Maximum excitation amplitude: ± 1 mm.
Mechanical strength: 2 g
Natural frequency: 6 – 8 Hz
Amplification factor: < 4
Temperature range: -90° to +300° C. 

Product Applications

Isolation of machines rotating at 800 rpm and over – fans, compressors, generating sets, engines etc. with or without seismic blocks. Protection of fragile equipment from vibrations. 

Note 

The mounts are delivered without mounting flange, which can be ordered separately. For greater static loads, use multiple element isolators (consult us).
