PAULSTRADYN ® Natural frequency : - axial : 7Hz - radial : 3 to 5,5 Hz Better than 90% isolation at 1.500 rpm (25 Hz). Constant height over wide load range. Stabilised characteristics during Service Life. Simple to fit. 500 hours protection against salt spray*. Design. *When mounted according to the recommendations given in the catalogue. Resilient Element = SILTECH - Low increase of stiffness with frequency - Low creep Finite element modeling (FEM) was used when designing the Paulstradyn® series resulting in the lowest possible elastomer stresses and most efficient performance for a high deflection mount of this type. APPLICATIONS Antivibration isolation for static equipment : - rotating machinery such as fans, air-conditioning, pumps, compressors, generator sets; - pipeworks, ceilings, transformers, electrical enclosures. 1) the indicated natural frequency, are valid for the maxi loads of the ranges of use quoted in the paragraph : TECHNICAL CHARACTERISTICS.

DIMENSIONS CHARACTERISTICS Shape 1 * Height, unloaded 40 mm, under load 32 mm (see Technical Characteristics). NL : Nominal static load with mounting under axial compression.

TECHNICAL CHARACTERISTICS The vibration attenuation and height characteristics under nominal loads are stabilised after one month under a load at 20°C. n Common characteristics n n Natural axial frequency : 7 Hz, with nominal load. Natural radial frequency : 3 to 5.5 Hz. Maximum displacement : - axial : 12 mm - radial : ± 10 mm. Vibration attenuation AL = Ratio ___________ actual load __ NL nominal load Attenuation coefficient (%) Height under load Stabilised height vs load Height under load (mm) AL/NL ratio (actual load/nominal load) Other characteristics* Good dynamic performance at high...
