ST Spring Isolator

Pre-loaded steel spring isolator delivering a 2 to 3 Hz natural frequency for very low frequency foundation isolation. High capacity units install beneath concrete inertia blocks and equipment bases, and factory pre-loading keeps installed height manageable during placement and grouting. Applied where elastomer or foam elements cannot reach the required isolation frequency, such as large presses and vibration-sensitive installations near heavy dynamic machinery.

• Natural frequency: 2 to 3 Hz
• Construction: pre-loaded steel spring isolator
• Load: high load capacity
• Packaging: per isolator, pre-loaded
