Vibration Pad Materials 

BILZ vibration isolation (anti-vibration) pad materials are highly developed, designed to solve problems caused in many industrial sectors by vibrations and structure borne noise. Made from a precise combination of nitrile rubber, cork particles and cross linked polyester fibers, these high grade compound materials possesses excellent physical and mechanical properties. One major advantage of these new compound materials are their resistance to modern cooling lubricants; the mountings can be used in oil sumps without any loss of their physical properties. Particularly worth mentioning are the superb “compression set” values. These are extremely important, for example, if modern machine tools are to be mounted in isolation while ensuring long term geometric position.  8 different types of pads provide the technically optimal solution to almost any vibration problem. The primary aim in the development of these vibration materials was to provide specific solution for a wide range of machinery for e.g. lathes, milling machines and grinding machines, as well as presses and feed presses!

Resistance to Aging

The service life of these mounting pads is nearly unlimited if the load values are observed. No permanent deformation will result.

Resistance to Chemicals

Extremely high degree of resistance to conventional oils, grease, acids, etc. Completely resistant to cooling emulsions, thus allowing machine mounting in oil sumps.

+ 120° to – 20° C

+ 250° to 5° F

Applications

Application Technology 1

Machine mounted on BILZ pads.  For machines that don’t require a high degree of mounting precision. Floor unevenness can be compensated for by using shim plates, etc. The plates are normally geometrically positioned. Size is determined on the basis of machine weight and available contact area.

Application Technology 2

Schematic illustration of floor anchorage using vibration isolation pad and washer. In some cases, it is necessary to anchor the object to be isolated to the floor. The use of vibration isolation washers (Accessories catalog page 15) prevents vibrations being transmitted via the screw connection. In particularly difficult cases, it is advisable to use adjusted disc springs. Size, etc. is determined by BILZ. 

Application Technology 3

Highly effective shock and vibration isolation using BILZ vibration isolation pad sets.  When isolating pulsating forces (presses, hammers, feed presses), BILZ pads are in this case combined to form pad sets (Isolated Foundation catalog pages 30). This helps to achieve extremely low natural vibration frequencies. Their great advantage over steel springs is their very high attenuation capacity; their ability to absorb and dissipate high amounts of energy.
