VIBRO STUD MOUNTS VRSM

Rubber Stud Mounts are vibration‑damping components designed to isolate and reduce the transmission of vibration, noise, and shock between machinery and supporting structures. Stud mounts or Rubber vibration dampers play a significant role in the reduction and isolation of vibrations from the machinery to the surroundings.

These mounts consist of a metal core (alloy steel) bonded with high‑quality rubber, offering excellent flexibility, durability, and vibration absorption. They are suitable for both static and dynamic applications across industrial, commercial, and domestic environments.

Shock‑absorbing mounts are available in multiple configurations—including single stud, dual studs, single tapped hole, dual tapped holes, or a stud‑and‑tapped‑hole combination—providing flexibility in how they are integrated into equipment. When a component requires support on only one side, a rubber bumper is typically more suitable. In such cases, the designer may select either a tapped‑hole or stud‑type interface, as mounting configuration has no significant effect on performance; damping characteristics are governed primarily by jacket durometer, height, and material composition.

In contrast, installing a vibration isolation mount is more complex because it must be secured from both ends. These mounts are designed to mechanically couple two machine components while simultaneously providing shock and vibration attenuation. Positioned between two structural surfaces, they stabilize the assembly and reduce transmitted dynamic forces.

It is important to note that vibration mounts are wear components and will require periodic replacement. The machine’s use of studs, tapped holes, or mixed interfaces influences both the initial assembly process and the ease of servicing when replacement mounts are needed.

There are several different vibration mount configurations to match a variety of application needs.

Vibration isolation Stud Mounts and rubber bumpers exhibit different damping and shock‑absorption characteristics due to variations in geometry and jacket material. Outer diameter, length, and material composition directly influence impact‑load performance. Larger‑diameter mounts accommodate higher impact forces but may be restricted by installation clearances. Longer mounts provide increased separation between components but typically withstand lower impact loads than shorter mounts of the same diameter.

Conical rubber bumpers offer superior impact‑load resistance through progressive energy absorption, providing a more controlled deceleration compared to standard cylindrical bumpers. This enhanced resilience, however, increases cost and may exceed the requirements of some applications.

Impact‑load capacity also correlates with jacket durometer hardness.

  • 40 Shore A: soft, high‑damping, lowest load capacity
  • 55 Shore A: balanced stiffness and damping
  • 70 Shore A: highest impact‑load resistance, increased rigidity

VIBRO MOUNT VMF

Floor isolation systems are incorporated into building design to minimize floor impact noise and airborne sound transmissions. Additional designed floor slab is supported by resilient mounts installed on the structural main slab. The design of an effective isolation system is dependent on several factors including: • Required Noise criteria to achieve. • Mass & Stiffness of the structural slab. • Isolation Mounts natural frequency and damping characteristics. • Space or Air gap to be created. • Design of the floated slab. • Control of Sound flanking paths. Creating air gap between the main and floated floors while decoupling the two floors with the appropriate resilient mount effectively reduce noise transmission. Airborne and impact noise transmissions are greatly reduced between the room incorporating the floating floor system and other floors of the building. VIBRO MOUNT floating floor systems offers the largest variety of isolation mounts with natural frequency as less than 10 Hz to fit specific applications.

MOUNT VMD ELASTOMER IN SHEAR ISOLATION

The Vibro Mount Model VMD delivers superior vibration isolation for suspended mechanical equipment, pipework, and ductwork installations. This engineered mounting system stops vibration transmission at the source, protecting building structures and occupants from disruptive mechanical noise.

Each VMD mount features a precision elastomer in shear insert with colour coded identification for easy load verification. Steel load caps with extended sleeves distribute forces evenly through the stamped transfer cap, ensuring stable support throughout the service life. This robust construction maintains alignment and performance even under continuous dynamic loading.

The shear configuration sets VMD mounts apart from traditional compression designs. Operating the elastomer in shear rather than compression allows significantly higher working strain before material degradation occurs. This fundamental design advantage extends service life while delivering consistent isolation performance. The elastomer experiences less fatigue stress cycle after cycle, maintaining its damping characteristics far longer than compression loaded alternatives.

Installation simplicity accelerates project timelines. The complete assembly arrives ready to install with no field adjustment required. Threaded connections accommodate standard hanger rods, integrating seamlessly into suspended systems. Colour coded inserts eliminate confusion during installation, ensuring correct load capacity selection throughout the system.

VMD mounts excel in applications where budget constraints demand cost effective solutions without performance compromise. Light mechanical equipment including HVAC components, pump assemblies, fan units, and distribution systems all benefit from the vibration isolation these mounts provide. The system prevents structure borne noise transmission that turns entire buildings into resonating surfaces broadcasting mechanical sounds throughout occupied spaces.

The elastomer in shear principle provides inherent advantages across the operating envelope. Natural frequency remains stable across the load range, delivering predictable isolation performance. Temperature variations affect performance minimally compared to compression designs. The shear configuration resists side loading better, maintaining position accuracy even when equipment experiences operational forces beyond pure vertical loading.

Durability comes from engineering fundamentals rather than exotic materials. The steel components resist corrosion in typical building environments. Elastomer compounds withstand normal temperature ranges without hardening or softening. Regular maintenance requirements remain minimal since the design eliminates adjustment mechanisms that drift or require periodic correction.

System designers appreciate the load range flexibility VMD mounts offer. Multiple elastomer stiffnesses cover equipment from light ductwork to substantial mechanical assemblies. Selecting appropriate mounts for each application point optimises isolation across entire suspended systems rather than forcing compromise through limited product offerings.

VMD mounts prove their value through reliable long term performance. Projects completed on aggressive budgets achieve professional isolation results that satisfy acoustic consultants and building occupants alike. The mounts continue performing year after year, maintaining the quiet environment that defines quality construction.
