Helical Shock and Vibration Isolators

Unlike traditional dampers that rely on rubber or elastomers, helical shock and vibration isolators manufactured by John Evans’ Sons use aircraft-grade stainless steel wire rope. The steel wire rope is wound into a helix and secured with metal retaining bars. 
This configuration offers:

High-performance damping. Coulomb damping of 15–17% of critical (C/Cc).Durable construction. All-metal design resists corrosion, temperature extremes, UV radiation, and more.Multidirectional protection. Isolates shock and vibration in compression, tension, shear, and roll across all axes.Wide load range. Cable diameters from 1/16” to 1” + support loads from a few pounds to thousands.

Key Benefits of John Evans’ Helical Shock and Vibration Isolators:

Maintenance-free and long-lastingExcellent resistance to harsh environmentsOperates in any orientationCustomizable cable configurationsSuitable for both light and heavy-duty applications
