Start with direction
Check whether the installation works in compression, shear or roll, or the 45° compression-roll direction used by the catalog tables.
Multi-axis shock and vibration isolation
Wire Rope Vibration Isolators
This family covers WR and CR wire rope isolators made from stainless steel cable and retaining bars for multi-axis equipment protection.

Working principle
Stainless steel cable bends and rubs under load, producing nonlinear stiffness and damping across compression, shear and roll axes.
Construction
Stainless steel cable, aluminum alloy or compact retaining bars, threaded or thru-hole mounting, optional bellmouth holes.
Applications
Transport equipment, electronics, marine installations, military equipment and harsh-environment mounting.
Selection notes from the catalog
Use load case, direction and deflection before choosing a wire-rope isolator.
Wire-rope isolators are selected from the catalog by the installed load, mounting direction and expected displacement. Use the product tables and curves as engineering inputs, then send the application data for review before treating a model as final.
Check the table values
Compare static load, maximum deflection, vibration stiffness Kv and shock stiffness Ks for the relevant WR or CR series model.
Prepare review data
Share load, mounting direction, available deflection, installation space and the shock or vibration environment so the application can be checked against the catalog evidence.
- Provide installed load, load direction, required isolation or impact case, available mounting space and environmental limits.
- Use the published dimensions and curves as catalog evidence; do not extrapolate missing models from similar appearances.
- State whether the duty is vibration isolation, shock isolation or combined machine protection.
- For unlisted conditions, send the machine data so engineering can confirm the suitable series and mounting option.
