Wire Rope Isolators (WRI)
To ensure safe and continuous operation, or for instance flawless and safe transport of (highly) sensitive equipment, adequate shock and vibration protection is essential. The adequate level of protection is typically predominated by combining the appropriate shock mounts, thorough calculation and understanding of the application. The advantage of a wire rope isolators (WRI) lies in its ability to combine a high level of isolation while taking up relatively little space. WRI are captive by their construction and may, for this reason, be loaded in any direction without the risk of malfunctioning. WRI are not subject to aging due to external factors such as oil, saltwater, chemicals, and heat or cold. Most applications of WRI can be found in situations where equipment needs to be mounted against shocks or vibration, but where sound isolation is of minor importance.
- Suitable for high temperatures
- Temperature independent performance
- Captive design
- Many variations available (dimensions, stiffness)
- Relative high damping grade
- Optionally coated for use in cleanrooms
- Switch cabinets
- Electronic equipment
- Small ventilation systems
- Equipment without vibration-source
WRI are constructed using an ingenious but relatively simple design. Steel wires are twisted into a cable, which is mounted between bars. Changing the thickness of the cable, the number of loops and the angle of mounting gives a specific behavior under a given shock and/or vibration load. This
way of constructing make sit possible to fine-tune the product to the specific requirements, even in case of low quantities. WRI can be supplied according to an almost unlimited number of specifications. Wire rope isolators are maintenance-free and are not subject to aging due to external factors like oil, salt water, chemicals and variations in temperature. Wire rope isolators are captive by their own construction.
