Key Specifications
These high-deflection, free-standing spring isolators feature large-diameter, laterally stable steel coils that are unhoused and engineered for optimal performance.
Product Details
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
- 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.
VRSIF shall consist of free-standing, large-diameter, laterally stable steel springs with a lateral stiffness greater than the rated vertical stiffness and designed to support a minimum overload capacity of 50%. Springs shall be assembled between top and bottom load plates, with the upper plate incorporating leveling bolts, locknuts, and washers for equipment attachment. Bottom plates shall include non-skid noise isolation pads and provisions for bolting to the supporting structure. Where required, isolators shall be housed in fabricated steel, with vertical restraints, neoprene snubbers, or internal pads to limit movement and prevent metal-to-metal contact. All housings shall be corrosion-resistant, either powder-coated, electro plated, or galvanized. Spring elements shall be powder-coated and rated for salt spray resistance when non-welded, and all springs shall be color-coded or otherwise marked for load identification. Springs shall be selected to provide the static deflections indicated in the Vibration Isolation Schedule or project documents.
VRSIF spring mounts are engineered to eliminate structural noise and vibration transmission from floor-mounted mechanical equipment into the building structure. These mounts are particularly effective in isolating low-speed machinery, where vibration and noise can otherwise propagate through structural elements, leading to discomfort, equipment wear, or acoustic interference.
