Rubber mounts and vibration dampers in the UAE are the rubber and rubber-metal elements placed under generators, chillers, pumps, compressors and engines to cut vibration and noise passing into floors and structures. This page explains the mount types, how to size them from load and running speed, how UAE heat and oil affect rubber, and what moves price and delivery.

A rubber mount is an elastomer element, often bonded to steel plates or studs, that carries a machine while allowing it to move slightly so vibration is not passed into the support. MAREK describes anti-vibration mounts as damping elements that absorb the vibration, oscillation and shock produced by machines, and calls rubber versions durable, with good cushioning that suits repeated impact. They are one product family within industrial rubber products in the UAE, alongside sheet, hoses and seals.
In practice UAE buyers meet them on diesel generator sets in tower basements and data centres, rooftop chillers and fan units, pump sets in district cooling plants, air compressors in workshops, and marine and mobile equipment. AMC Mecanocaucho lists a wide set of forms: rubber-to-metal isolators, rubber pads, bushings, sandwich and stud mounts, rubber stops, machine feet and conical mounts, plus captive and restrained designs, high-damping types, hydraulic isolators, marine engine mounts and cab mounts.
| Mount type | Typical UAE use | Selection points |
|---|---|---|
| Rubber-to-metal stud or sandwich mount | Compressors, pumps, small generators, fans | Load per mount, stiffness in compression and shear, thread size |
| Conical or cup mount | Engines and gensets where load and tilt act together | Stiffness in each direction, restraint against overload |
| Rubber pad or strip | Light machinery, plant room equipment, pipe supports | Pad thickness, hardness, bearing area |
| Captive or restrained mount | Mobile, marine and seismic-sensitive equipment | Fail-safe retention, bump stop clearance |
| Rubber buffer or bumper | End stops, shock loads, doors and guards | Shape to DIN style, Shore A hardness |
MAREK states that its standard hardness is 55 degrees Shore A, with other hardnesses on request, and that its shapes and sizes follow DIN standards with internal or external threads. Soft mounts isolate more but deflect more under load, so hardness is part of the sizing, not an afterthought.
Size a mount from the load on it and the lowest frequency of vibration you want to isolate. Karman Rubber sets out the sequence: find the load each mount carries (the total load divided by the number of mounts if it is evenly shared), find the lowest disturbing frequency from the running speed, choose the natural frequency that gives the isolation you want, work out the static deflection and spring rate, then pick a mount whose rating is at or above the load and whose spring rate is below the calculated value.
Karman defines isolation efficiency as 1 minus transmissibility, and states that 80 per cent is generally considered satisfactory, with transmissibility of 20 per cent or less normally desired. A 1,500 rpm generator and a 750 rpm pump do not need the same mount, because the lower the running speed the softer the mount has to be. For very low frequencies or heavy loads, rubber may not deflect enough, and engineers move to steel spring isolators; AMC Mecanocaucho lists spring isolators for low frequency isolation of machinery and HVAC equipment alongside its rubber range.
Karman warns that overloading a mount may lead to premature failure, while excessive underloading will not deflect the mount enough to isolate. A mount is not a better mount for being stiffer. Check the real weight distribution, including the centre of gravity of a genset with its fuel, and give the supplier the running speed range, including start-up and coast-down, where a machine passes through resonance.
Rubber ages with heat, ozone, sunlight and oil, and UAE conditions test all four. Plant rooms and rooftops run hot for much of the year, direct sun degrades unprotected rubber surfaces, and generator and compressor mounts sit where oil drips collect. Karman notes that natural rubber suits most industrial applications but is affected by oil immersion, and that neoprene resists oil and tolerates higher temperatures than natural rubber, giving about 150 degrees Fahrenheit for natural rubber and 180 degrees Fahrenheit for neoprene as maximum operating temperatures.
Use those as a screening guide and check the exact compound with the maker. Where a mount sits next to an engine exhaust or a hot oil line, ask for the compound's rated temperature and fit a heat shield. Stainless steel metalwork is worth specifying for coastal and washdown sites, since AMC Mecanocaucho offers stainless versions for demanding environments. Outdoors, mounts under chillers on a rooftop need covers or a compound with ozone resistance, and any mount should be inspected for cracking or permanent set at each planned maintenance visit.
No UAE product certificate is specific to anti-vibration mounts as of 2026. The requirements come from the machine maker, the building services or acoustic specification and the client's engineering standard.
| Requirement | Applies to | Who sets it |
|---|---|---|
| Machine maker installation instructions | Type, number and placement of mounts under a supplied machine | The equipment manufacturer |
| Project vibration and noise criteria | Plant rooms, rooftop equipment, residential towers | The acoustic consultant or MEP engineer |
| Shape and size standards for buffers and mounts | Standard catalogue parts, for example DIN dimensions | The mount manufacturer |
| ECAS or EQM conformity | Only if a supplied item falls under a MoIAT regulation; see our guide to ECAS and EQM | MoIAT |
Treat the manufacturer's laboratory and field test data as part of the submittal. AMC Mecanocaucho says product data includes laboratory and field test results and lets users filter by load type, stiffness per axis, damping and environment. Verification after installation is done by measurement, using vibration sensors on the machine and the floor.
Buy engineered isolators for large or critical machines from a manufacturer or its authorised UAE agent that will check your sizing, and use stockists for standard studs, pads and buffers on lighter equipment.
Machines often need more than mounts to be quiet: flexible connectors on pipes such as rubber expansion joints, and seals such as rubber seals and gaskets at the covers. To collect quotes from several UAE suppliers, post your requirement with the machine data.
Price rises with load rating, size, the metal parts, stainless or special coatings and the compound. Standard catalogue mounts are cheap and often in stock, while engineered or restrained isolators are made to order and need a sizing calculation first.
Lead time depends on whether the part is stocked in the UAE or shipped from abroad, and whether an acoustic consultant must approve the submittal. Ordering mounts together with the machine avoids a late surprise on site.
