ELESA vibration-damping levelling elements have been designed to damp vibrations, shocks and noise produced by moving bodies or non-balanced vibrating masses of equipment and machines which can cause:
- malfunction and reduction of the machine lifespan and/or of the adjacent ones
- damages at men’s health
- noise.
LW.A are made up of three main elements: zinc-plated steel base with natural rubber disk, zinc-plated steel levelling disk and threaded stem to allow an easy and precise levelling of the machine.
Vibration-damping levelling elements are available in the following diameters: 80 - 120 - 160 and 200 mm.

The OSM-Series mount is designed for use on machinery that does not require fastening to the floor and where stringent demands are imposed on effective vibration damping and the reduction of troublesome noise emitted from machinery and equipment.
It has been designed with the aid of FEM analysis, which prevents
fatigue from fast working cycle times and strong lateral forces in heavy machinery.
The reinforced leveling bolt support cup distributes machine loads to
the support points within the mount. The leveling element provides
direct and reliable machine mounting to suit most installation needs.
Vertical as well as horizontal forces are dampened out by
the integral nitrile pad, which also provides chemical resistance
to most fluids.
A tried and tested design with good leveling characteristics
makes the OSM-Series the natural choice for the majority of
machine types used in industry.

As the name implies, it is a device that prevents one object from affecting another. It allows both objects to exist in their natural state without influence from the other. With an isolator, one of the objects is allowed to vibrate without transmitting all of the energy of that vibration to the other object.
For many years, Firestone has been in the business of designing and developing a wide range of mounts and supports to isolate vibrations that are detrimental to many industrial and manufacturing environments. The range of isolators offered by Firestone has been redefined to include two major lines of isolators - Firestone Airmount isolators and Firestone Marsh Mellow springs. Each have their distinct benefits over other typical industrial vibration isolators, and each has advantages over the other. Many industrial vibration isolation problems can be solved using either line, and a complete analysis of potential solutions to these problems should include investigating options using both lines of isolators.

Large gas and diesel engines are used for many purposes, i.e. trains, ships and for local power generation. In all cases, foundations for these engines must be both economical and effective. Elastic support of this equipment meets these requirements.
During operation, some of the oscillating forces and moments generated by the engine are balanced internally; remaining forces and moments are transmitted into the foundation.
|
|
Pumps may rotate or reciprocate. Rotating pumps are usually well balanced. Nevertheless their elastic support makes sense when these pumps are installed on the upper floor levels inside a building, since in this way vibration and structure borne noise can be avoided.

Precision machine tools like Roll Grinders, Machining Centres, 3-D Measuring Machines, Microscopes or Test Equipment, located typically in the middle of a plant, are often sensitive to vibrations, excited somewhere in the surroundings.

The Air Spring Insulator BiAir consists of a cast steel or aluminum housing, within which the air space is contained by thin-walled flexible and pressure-resistant rolling membrane. A piston sits on top of the membrane and is pressed into the air space. This design allows a highly-effective isolation of vibration. In order to simultaneously achieve a high degree of damping, the air space is divided into two chambers connected with an air tube. (load/damping volume) A choke valve can be used to adjust from outside the cross-section of air flowing into the connecting tube from outside according to the degree of damping required. The friction on the flow of air caused by the choke valve can create a damping effect of up to 20%. Damage to the rolling membrane caused by overpressure is prevented by additional safety valves. Air springs are available for greater maximal loads and lower natural frequency. Level control provides an important contribution toward the optimal function of an air spring system. If a change in load likely occurs on equipment mounted with an air spring system, such that compression of one of the springs or an inclination of the equipment will result, a leveling system might be the only solution available. The change in air pressure in the air spring insulators adjusts the height of the individual elements (BiAir or FAEBI). By quickly pressurizing or de-pressurizing the springs, the proper level can be maintained despite variations in the position of the load.

Air spring type SLM
Material elastomer part: CR with steel insert, black
Material base plate: aluminium
Product description: The air springs are based on an elastomer body reinforced with a steel ring. It enables an effective oscillation insulation. The elements are specified primarily of the frequency ratio and dynamic forces.
Execution: Depending on build height and load a natural frequency is reached between 3 and 5 Hz. By increasing or reducing the air pressure, the object can be leveled to the working height H.
Application: They are suitable for passive insulation of scales, gauges etc. also for the active insulation of slow running devices such as ventilators, compressors etc.
Assembly: Adhere to the assembly instructions!
Attention: SLM-elements may only be placed under load and according to type with maximal 4 to 5 bar of pressure. A load on the full surface is permit even w/o pressure. The specified load capacity Fz is valid for the maximum static load.

The Fabreeka® Precision-Aire™ PLM series pneumatic/elastomeric isolation mounts are low frequency vibration and shock isolators which provide both attenuation of disturbing vibration and equipment leveling.
For vibration control applications, the pneumatic portion of these mounts provides isolation of vibration occurring at frequencies above 5.0 Hz.
For shock or impact applications, the outer elastomeric wall construction provides a high deflection shock mount. A low natural frequency (3.0 Hz) can be maintained by utilizing an external spacer to prevent "bottom out" condition.
Some features and benefits of PLM mounts:
PLM isolation mounts will continue to isolate with no pressure having a vertical natural frequency of approximately 10.0 Hz
The vertical to horizontal natural frequency ratio is approximately 1:1 with a degree of horizontal stability
1/8 NPT female fitting molded into sidewall allows for tank valve or pneumatic fitting
Viscous damping option provides increase in damping for large dynamic inputs.
