511110 is a classic single male-stud cylindrical anti-vibration isolator belonging to Hutchinson Paulstra’s renowned Radiaflex® product line, manufactured in France with mature vulcanization technology. Constructed of high-bonded natural rubber and plated mild steel housing, this unit features an outer diameter of 12.5 mm and overall height of 10 mm with an integrated M5 external threaded stud for direct equipment mounting. It delivers a rated maximum compression load of 12 daN and standard compression deflection of 2 mm, operating reliably within the temperature range from -20°C up to +70°C. Distinctively engineered with higher radial elasticity than axial elasticity, the isolator works under axial compression, radial shear or combined compression-shear based on installation layouts to cut down machine vibration and structure-borne noise efficiently.
