Noise reduction and vibration isolation are important factors in the design of workplaces and in production facilities. Preventative vibration isolation not only improves working conditions for people and their environments, but also increases product quality and production speed, gives companies a competitive advantage and achieves more accurate measuring results.

When it comes to vibration isolation, a distinction is generally made between source and recipient isolation. With source isolation, a machine is isolated from its substrate and the vibrations can therefore be damped to the required level. With recipient isolation, an object is protected from the transmitted vibrations. Depending on requirements, extremely lowfrequent isolating air spring elements, ready-to-install rubber-metal isolators or damping pads can be used for this.

Vibration isolating pads

The wide range of types of pads provides users with optimum vibration control technology in all areas. As the pads are cut to customer’s requirements, made-to-measure insulation is therefore possible. Three different products are available as vibration-isolating pads.

  • SLAB are universal damping pads, produced according to a patented formulation of PUR materials.
  • CEL pads are made of nitrile rubber and several layers can be glued together.
  • PADs are robust fibre and elastomer pads, consisting of several layers, which are suitable for many different heavy-duty applications.

SLAB 170 to SLAB 720

Series SL-170 to SL-720 vibration isolating pads are universally applicable as absorbers and are made of flexible, highly cushionable PUR materials. The pads are 12.5 mm or 25 mm thick and available with a density of 170 kg/m² to 720 kg/m².

SLAB pads can be individually combined and custom-made to suit requirements. Their natural frequency lies between 12 Hz and 50 Hz, and their load range is between 0.002 N/mm² and 0.5 N/mm².  These pads are used as foundations for plant and machinery, compressors, pump stations and generators.

Low-frequency damping CEL type pads avoid harmful vibrations, isolating objects from the floor or foundations. The panels are made of nitrile rubber and are available in the standard thicknesses 12.7 mm, 25.4 mm and 50.8 mm.

CEL pads can be glued to floors, reducing vibrations and noise to a minimum. They can also be individually combined with other insulation packages. The natural frequency of CEL pads lies between 11 Hz and 60 Hz, and their load range is between 0.35 N/mm² and 2.1 N/mm².

PAD fibre and elastomer pads can be produced as pads, washers or bushings. They provide the ideal combination of isolating elastomer layers and resistant fibre inlays, and so are ideal for heavy-duty applications. Impacts and shocks are cushioned effectively, and vibrations and structure-borne noise are isolated.

PDA can withstand compressive loads up to 69 N/mm², depending on their form and size. The material, which is built up in layers, displays first-class compression properties and a low creep tendency. The natural frequency of PAD pads is only for shock absorbency, and their load range lies between 0 N/mm² and 13.8 N/mm².

These series COM pre-tensioned high-performance equipment mounts isolate machines and plant in a vertical direction. The compression mounts are extremely robust elastomer mounts, which are primarily used in heavy-duty applications. COM vibration isolators have a low natural frequency of approx. 8 to 15 Hz.

Isolating interference frequencies about 900 rpm prevents negative impairment of the environment through impacts and vibrations from unbalanced machine components. These compression mounts isolate structure-borne noise, are robust and maintenance-free. COM are used in centrifuges, ventilation systems, compressors, injection moulding systems and switch cabinets.

Low-frequency pneumatic levelling mounts

Low-frequency pneumatic levelling mounts are used to guarantee the highly effective isolation of measuring benches, high-performance machines and test facilities. Individual solutions can also be developed to achieve perfect isolation. Two different ACE pneumatic levelling mounts are available to choose from.


PLM pneumatic levelling mounts are used for low-frequency vibration and shock isolation. They enable measuring tables, coordinate measuring machines, ventilation systems, motor units and high-speed presses to be protected from vibrations.

PLM isolators effectively reduce unwanted vibrations, at the same time perfectly levelling the equipment. Their natural frequency lies at 3.0 Hz in optimum loaded conditions. Thanks to their vulcanised threaded insert, the levelling mounts can either be blown up using a standard tyre valve or a pneumatic threaded connection. These air springs are used, among other things, on measuring tables, test stations or in production plants.

Pneumatic levelling mounts with automatic level control (PAL) provide optimum lowfrequency vibration isolation for measuring equipment, test and vibration equipment, coordinate measuring machines and precision production machines.

PAL air spring systems use level-controlled air springs and are therefore particularly suitable for applications that simultaneously demand constant levelling and vibration isolation. Standard PAL isolators have a natural frequency of up to 1.7 Hz. These air spring elements are used, among other things, on measuring tables, test stations, on aircraft and automotive test rigs and in foundation mounting.
