High performance vibration dampers

High performance vibration dampers - Features and guidelines for the choice General information High performance vibration dampers are used in compliance with safety regulations on vibrations and noise (DL 81/2008). The use of this product range allows: to prevent damage to structures, to preserve the correct operation of sensitive equipment, to reduce noise. Features AVC: • High static deflection, low resonance frequency and high vibration isolation. • High damping, also suitable for machines with imbalances. • Suitable for use with with compression, traction and shear. • Suitable for...

With reference to the graph below the products that intersect the 1400 N line are: AVF AVG, AVM. , For the 1400 N load, the expected static deflections are: • AVF: approximately 4 mm (< 7 mm) = approximately 80% isolation at 20 Hz • AVG: 6.5 mm (< 7 mm) = approximately 88% isolation at 20 Hz • AVM: 13 mm (< 7 mm) = approximately 95% isolation at 20 Hz Consequently, the most suitable product with the best isolation degree is AVM.

Wire rope isolators INOX STAINLESS STEEL Stainless steel CABLE, BARS AND SCREWS AISI 316 stainless steel. STANDARD EXECUTIONS Threaded pass-through holes. - AVC-4: the cable extends for four loops. - AVC-6: the cable extends for six loops. - AVC-8: the cable extends for eight loops. FEATURES AND APPLICATIONS AVC wire rope isolators are composed of two pairs of bars, joined together by a connecting cable with a helical winding (loop). They are generally used for isolating vibrations and shock absorption, where axial holding force, resistance to compression and shear force is required....

Spring mounts BODY AND NO-SLIP COATING NBR rubber. Hardness 60 Shore A ±5. SPRING AND PLATE Zinc-plated steel. SPRING CAPS Aluminium. FEATURES AND APPLICATIONS AVM spring mounts comprise a body and a non-slip coating fixed to the lower part with a zinc-plated screw, and a spring on which two caps with pass-through holes at the ends are fixed. They are generally used for vibration isolation in compression. Vibrations can cause: - malfunctioning and reduction of the machine lifespan and/or of the adjacent ones; - damage to health; - noise. They are particularly suitable for use with HVAC,...

Metal Cushions INOX STAINLESS STEEL Stainless steel MESH AISI 304 stainless steel. STANDARD EXECUTIONS - AVF-A: plain pass-through hole. - AVF-SH: plain pass-through hole for countersunk-head screws. FEATURES AND APPLICATIONS They are generally used for vibration isolation in compression. Vibrations can cause: - malfunctioning and reduction of the machine lifespan and/or of the adjacent ones; - damage to health; - noise. They are particularly suitable for use with thrusters, electromechanical equipment, industrial refrigerants, pipe supports, flooring and train carriage panelling. See High...

Metal Cushions The min. load is the value below which the vibration damper is not able to isolate the vibrations as it would be too rigid. The max load is the value beyond which some type of failure may occur that compromises the functionality of the vibration damper. The min.deflection is the crushing of the vibration-damping support corresponding to the min. load. The max.deflection is the crushing of the vibration-damping support corresponding to the max. load.
