Rubber mounts and vibration dampers in Saudi Arabia are the rubber and rubber-metal isolators under compressors, pumps, generator sets, crushers, fans and engines that cut vibration and structure-borne noise. This page explains the types, how to size them from weight and running speed, what Saudi heat and oil do to the rubber, and what to ask a supplier before ordering.

A rubber mount is an elastomer element, often bonded to metal plates, that stands between a machine and its foundation. It lets the machine move a little so that vibration is absorbed instead of passed on to concrete, steel frames and nearby equipment. MAREK defines anti-vibration mounts as damping elements that absorb vibration, oscillation and shock produced by machines. They belong to the wider rubber products sold in Saudi Arabia.
Saudi uses run from reciprocating compressors and large pumps in petrochemical and gas plants to diesel gensets at construction camps, crushers and screens in mining and quarrying, chillers in district cooling, and truck and cab mounts on mobile equipment. AMC Mecanocaucho shows the range of forms a maker may offer: rubber-to-metal isolators, pads, bushings, sandwich and stud mounts, conical mounts, stops, machine feet, restrained and marine designs and hydraulic isolators.
| Application | Common mount style | What decides the choice |
|---|---|---|
| Crushers and vibrating screens | Heavy rubber-metal or buffer elements | Shock load, dust, bump stops, access for replacement |
| Generator sets and engines | Conical or cup mounts, restrained designs | Oil, heat, tilt and torque reaction |
| Pumps and compressors | Stud or sandwich mounts, pads under skids | Running speed, load per point, piping loads |
| Chillers and air handling units | Rubber-metal mounts or spring isolators | Low frequency isolation, roof or slab limits |
| Mobile equipment cabs | Cab mounts and restrained isolators | Multi-axis stiffness, fatigue life |
Sizing starts from weight and speed. Karman Rubber lists the steps: work out the load on each mount, take the lowest disturbing frequency from the running speed, decide the natural frequency needed for the isolation you want, calculate static deflection and spring rate, and choose a mount whose rated load meets or exceeds the load per mount and whose spring rate is below the calculated figure. It then asks you to check transmissibility using the actual spring rate of the mount you picked.
Karman states that 80 per cent isolation efficiency is generally considered satisfactory, meaning transmissibility of 20 per cent or less. Lower running speeds need softer mounts, so a slow compressor is harder to isolate than a fast fan. Rubber suits many industrial machines, but heavy loads and very low frequencies can need springs, and AMC Mecanocaucho lists spring isolators for low frequency isolation of machinery and HVAC equipment.
Karman warns that overloading may lead to premature failure and that excessive underloading will not deflect the mount enough to isolate. For skid-mounted equipment, take the operating weight (with fluids), not the dry weight, and note that a piece of equipment bolted to rigid pipework cannot move freely, so connect with flexible joints such as rubber expansion joints.
Hot summers, desert dust, sun and oil leaks shorten rubber life. Karman states that natural rubber suits most industrial applications but is affected by oil immersion, and that neoprene resists oil and tolerates higher temperatures, with maximum operating temperatures of about 150 degrees Fahrenheit for natural rubber and 180 degrees Fahrenheit for neoprene. Use those as screening values and confirm the compound with the maker for hot engine rooms and for mounts close to exhausts.
Dust packs into crevices around mounts under crushers and screens and can stop a mount from moving as designed, so ask about covers or open designs that shed material. In coastal sites around Jubail, Yanbu and Jeddah, salt attacks plain steel parts; AMC Mecanocaucho offers stainless steel versions for demanding environments. Check mounts at each planned shutdown for cracks, bulges and permanent set, and keep spares for machines that cannot stop for long.
As of 2026 there is no certificate specific to rubber mounts for industrial use in the Kingdom is known. The requirements come from the machine maker, the client specification and, for buildings, the acoustic design.
| Requirement | Applies to | Who sets it |
|---|---|---|
| Machine installation manual | Mount type, count and positions for a supplied machine | The equipment manufacturer |
| Owner or EPC vibration specification | Skid foundations, rotating equipment and structures | The plant owner |
| Manufacturer dimension standards | Catalogue mounts and buffers, for example DIN shapes | The mount maker |
| SASO and SABER conformity | Imported goods that fall under a SASO technical regulation; see our guide to SASO and SABER certificates | SASO |
Whether an imported rubber mount is classified under a technical regulation depends on its SABER registration, so ask your importer. MAREK notes that its shapes and sizes follow DIN standards and that its standard hardness is 55 degrees Shore A, which is useful when matching a replacement. Confirm results on site with vibration sensors or a measurement survey.
For critical rotating equipment, use a supplier that will review the sizing and supply test data. For standard buffers and pads, a stockist with local inventory is faster.
Related items on the same machine include rubber seals and gaskets. To compare Saudi suppliers, post your requirement with the machine data.
Price follows load rating, size, metalwork, coatings and the compound. Stock catalogue items are inexpensive, while engineered or restrained isolators are made to order.
Lead time depends on stock in the Kingdom, import clearance and whether a consultant must approve the submittal. Order mounts with the machine so the skid can be assembled and levelled on time.
Most field problems are installation problems. Mounts are fitted unevenly so one carries more than its share, anchor bolts are over-tightened so the rubber is pre-loaded, pipework and conduit are connected rigidly and short-circuit the isolation, or a skid is levelled with packing that bridges the mount. Each of these defeats the isolation even when the mount is correctly sized. Check that all mounts show similar deflection under load, that nothing rigid touches the machine, and that bump stops have the clearance the maker specifies.
A second group of problems appears at start-up and shutdown. Every isolated machine passes through its natural frequency as it speeds up, and a lightly damped mount can let the machine rock noticeably during that moment. High-damping mounts or restrained designs, both listed by AMC Mecanocaucho, are the usual remedy for equipment that starts and stops often. Record the vibration level at commissioning so you have a baseline for later comparison.
