VIBRO ISOLATOR VRSHI

VRSIH housed spring isolators are high-performance vibration control units designed to deliver substantial deflection while maintaining structural restraint. Each unit incorporates large-diameter, laterally stable steel springs housed within a fabricated steel enclosure to prevent excessive movement and ensure safe operation under dynamic, seismic, or wind-induced conditions. The spring assembly is mounted between precision-engineered top and bottom load plates. The upper plate includes integrated leveling bolts, locknuts, and washers for accurate equipment alignment and secure attachment. The bottom plate features a non-skid neoprene isolation pad and bolt provisions for anchoring to the supporting structure.

VIBRO ISOLATOR VRSIF

These high-deflection, free-standing spring isolators feature large-diameter, laterally stable steel coils that are unhoused and engineered for optimal performance. Each spring assembly is integrated into a robust upper load plate with a precision leveling mechanism to ensure consistent load distribution and ease of installation.
  • Light-Duty Configuration: For lower load capacities, the isolators are equipped with molded neoprene bottom load plates, offering effective vibration damping and acoustic isolation.
  • Heavy-Duty Configuration: For higher load applications, the steel springs are securely welded to a heavy-gauge steel bottom load plate. A neoprene isolation pad is bonded to this plate to enhance vibration attenuation and reduce structure-borne noise.
Technical Features and Performance Criteria:
    • Spring Geometry: The ratio of spring diameter to compressed height under rated load is maintained at a minimum of 0.8, ensuring lateral stability and consistent performance.
    • Corrosion Protection: Springs are finished with an epoxy powder coating, tested to withstand up to 1000 hours of salt spray exposure for enhanced durability in harsh environments.
    • Acoustic Isolation: A neoprene friction pad is incorporated to act as a sound break, effectively minimizing the transmission of high-frequency vibrations.
    • Vibration Isolation Efficiency: The system achieves a vibration isolation efficiency exceeding 95%, making it suitable for sensitive equipment and noise-critical installations.
    • Structural Integration: Bottom plates are pre-engineered with bolt provisions to facilitate secure anchoring to the supporting structure.
    • Stability Assurance: Lateral stiffness of the spring assembly is designed to exceed 1.0 times the rated vertical stiffness, ensuring reliable performance under dynamic loads.
    • Overload Capacity: Each spring unit is rated to accommodate a minimum of 50% overload beyond its nominal load capacity. Springs are structurally safe even at solid height compression.

VIBRO ISOLATOR VRSIR

VRSIR Restrained Spring isolators are designed to deliver high-deflection vibration isolation while incorporating structural containment features that prevent excessive movement under dynamic or seismic conditions. These units utilize large-diameter, laterally stable steel springs housed within a rigid frame that limits vertical and horizontal displacement, ensuring safe and predictable performance in demanding environments. Each spring assembly is integrated into a heavy-duty upper load plate with a built-in leveling mechanism, allowing for precise load distribution and simplified installation. The restrained design ensures that the spring remains securely seated throughout its operating range, even under transient or overload conditions.
