VIBRO-SMR – Vibration Isolation for Heavy Machinery

VIBRO-SMR is DECIBEL’s high-performance anti-vibration spring mount engineered for low-frequency vibration and noise control and multi-directional restraint in industrial and HVAC applications. Built for stability under the most demanding conditions, it effectively absorbs vibrations from heavy equipment operating at 400 RPM and above, while offering protection against seismic forces, wind pressure, and external impacts.

Manufactured from durable, corrosion-resistant steel, VIBRO-SMR combines strength with advanced engineering design. Its adjustable height mechanism allows for perfect machine alignment during installation, while the rubber base profile ensures additional isolation of high-frequency noise. This makes VIBRO-SMR the ultimate choice for compressors, chillers, air handling units, and other dynamic systems exposed to structural stress.

How It Works

VIBRO-SMR integrates a precision-engineered steel spring, compliant with ISO EN 10270 standards, that isolates low-frequency vibrations from heavy rotating or oscillating machinery. The spring’s vertical flexibility absorbs compression and tension loads, while its lateral restraint bars stabilise the unit against seismic or wind-induced movement.

An elastic rubber gasket separates the metal surfaces, preventing sound bridges and improving high-frequency isolation. The base profile, made from weather-resistant rubber, acts as a secondary damper for airborne and structure-borne vibration transmission.

With its innovative welded steel frame, the design reduces the number of weld points to enhance mechanical strength and durability, ensuring long-term performance even in harsh outdoor or industrial environments.

Key Benefits

• Provides low-frequency vibration isolation for heavy-duty machinery (400 RPM+).
• Delivers multi-directional restraint against seismic events, wind pressure, and external loads.
• Built-in height adjustment system for precise machine alignment.
• Complies with ISO EN 10270 for spring design and durability.
• Rubber base profile enhances high-frequency isolation and outdoor resistance.
• Elastic gasket prevents metal-to-metal contact and sound transmission.
• Constructed from powder-coated steel for maximum corrosion resistance (galvanised version optional).
• Long-lasting performance with minimal maintenance requirements.

Installation Overview

VIBRO-SMR mounts are designed for secure, floor-mounted installation beneath heavy machinery. Two mounting holes at the base allow easy anchoring with standard bolts, while the top connection bolt ensures precise load distribution.

The adjustable height system facilitates levelling during setup, ensuring stable machine operation and balanced spring compression. Once installed, the mount immediately provides isolation and restraint in both vertical and lateral directions.
