There are different kinds of anti vibration rubber mounds. Some of them are used in marine and mobile fail safe. Fail safe protection is offered by this kinds of mounds and is used and applied in all mobile engine applications. The different applications are pumps,

diesel genset, marine propulsion engines and compressors. They are available in different size range such as 88 to 1760lbs. They are often interchangeable to Metalastik Cushyfloat type and Novibra SIM type mounts. All mounts are designed in such a way that they have adjustable heights according to need. The profile maintained by the fail safe mounts are low and the install design is quite easy. There is an integral fail safe designed assigned which acts as shock provider. This device all gives failure protection to marine and mobile auxiliary engine applications. Pumps, compressors and garnets are included in these applications. There are also different size ranges for fail safe mounts, ranging from 66 to 11,000 lbs. Like marine engine mounts they can also be interchangeable at Matalastik Cushyfloat type mounts. Even for corrosive environment stainless steel is available which has a size range from 55 to 160 lbs.
The next category is the HVAC Mounts or Anti Vibration Stationary Machine. This mount is very useful for isolating low frequency vibrations from all kinds of plains. They have also been very productive for shock absorption since it carries the ability to absorb large deflection. They can be applied to different applications such as vibrating tables, HVAC equipments, fans, compressors and electric motors. Novibra Type M mounts could be interchangeable through this. Different types of mounts under this category include
Vibration rubber mounds
Bumper Mounts, Flex Mounts, Ring Mounts and Rail Mounts. There is also a default custom set up where the cut to length option is available. These are also drilled with tapped holes. These holes are also made according to specifications. Enclosure Mounts or Anti Vibration electrical panel are used for electrical cabinets which can be wall mounted. These could be used for both stationary and mobile applications and have distributing frequencies. Tension or shear could be used to load the upper mount. The lower mount on the other hand is used to load compression or in shear. Other types of mounts include Pipe hanger Mounts. These could be used for hanging pipes and machinery form ceiling and are used for isolation vibration and noise. Bushing mounts on the other hands provides a interface which is between two different parts used for damping transmitted energy which is used through the bushing.
A rubber busing or busing is a popular type of vibration isolator. It provides an interface between two different parts and in return energy is transmitted through the bushing. They are commonly applied in vehicle suspension system. Rubber is used to make the bushing

and sometimes polyurethane and synthetic rubber is used to make the bushing. The bushing separates the two metal objects and a certain amount of movement is allowed. The suspension parts are moved freely through the movement provided by the bushing. A common example is travelling over a large bump this bushing helps in minimizing transmission of small vibrations and noise. This is also known as anti vibration mounting or flexible mounts.
The main advantage of a bushing in comparison to a solid connection is producing less vibration and noise transmitted. Another major advantage is that no lubrication is required by them. However on the other hand there are a lot of disadvantages. There is a high possibility of detonating which can happen in presence of oil. Cold and extreme heat could also provide to be a treat. The flexibility of rubber may also decrease in certain instances.
Bushing rubber mounts
This could highly affect the handling of the vehicle. Busing isolator could be used and applied in a number of ways. In vehicles it is used in Sway bar mounting and links, Shock absorber mountings. It is also used in Double wish bone suspension mounting. It is also used in gear sticks present in vehicles with manual transmission. This isolator is also present in Norton Commando motorcycle. One of the famous applications is in the skate boards where this is used to turn the board. Bushings are also used in fastening which is useful for transferring loads into larger areas. In the underlying structures it is present to reduce the strain of the individual fibers. It is also popularly used in balancing crankshaft. Some high speed and combustion internal engines are balanced which are often prone to the crankshaft’s tensional vibrations.
The busing isolator has the form of an annual cylinder carrying a flexible material present inside an outer tube or metallic casing. There is also an internal crush tube which holds the fixing in the threaded spigot. Different types of designs are available. This kind ofvibration rubber mount has a major difference with plain bearings. The two parts are connected by a rubber which controls the relative motion and not by fiction and shear at the interface.
Andrehvac vibration isolation hangers help reduce problem.
Spring isolator hangers have a large diameter along with stabile and freestanding steel springs. A molded fiber glass which is recompressed is also assembled and inserted into a welded or stampede hanger bracket. No short spring cap is also present with 1” and 2” kinetic patterns. This is very important because it ensures stability. The lateral spring has a stiffness of about 1.0 times. The spring isolator models are built to have advanced and superior features than its previous models. It has a capability of carrying 500% workload and this can be done without any kind of failure. The spring present can be useful in transmitting noise through any kind of metal construction. There is a low frequency transmit which could be isolated by the spring only. There are different deflation available ranging from 1.04 to 2.02. Their capacity starts form 35 and can extend up to 3850lbs. They can isolate the vibration which is produced by suspended mechanical equipments such as pumps, low speed fans, piping and ductwork.
SH Series spring isolator hangers are also popular along side. They have mainly springs made of steels which can be kept in rectangular steel brackets. Steel and Elastomer’s
dual incorporation is used to distribute load uniformly. These also have high frequency isolation. Their main use is to control both vibration and noise. The brackets are blue power coated and there is hot dip galvanized spring. It has been designed in such a way that angular hanger misalignment is allowed. It is also absent from nuts and hanger rods. These SH series spring isolator hangers have different applications. They could be used in fn coil units and is of great help in reducing vibration and noise. They also have wide application in Air handling units. Other than this it is also used in pipes, fans and ducts. In this system roofs, ceilings and structural boards acts as sounding boards. These vibrations are transformed into audible noise. In this case Vibro Acoustic is quite useful in reducing the vibration. The springs are designed uniquely which is used to operate low frequency vibration. The elastomeric are used as low frequency vibration. This is very useful in absorbing high frequency vibration. Both the operators are combined so that the performance is maximized. Other kinds of hangers are precompressed spring hangers, spring hangers and neoprene hangers. Spring ceiling hangers are also popular and very much in use.
