Bordignon’s Nitrogen Gas Springs are long-lasting and reliable as the result of many-year experience, research and innovations, values awarded with UNI EN ISO 9001 Certification. When correctly used, Bordignon’s Springs have a duration of 200.000.000 mm of total stroke under normal working conditions.Bordignon’s Nitrogen Gas Springs are realized with single or “monolithic” mechanical parts singoli with high width, to guarantee the integrity of the product and the maximum safety for the user even in the most extreme conditions of incorrect application. The rod is blocked by a high-width mechanical stopper inside the body of the gas spring. Moreover, in case of extra-stroke or excessive internal pressure, the metal shell of the body of the gas spring, slimmer at its base, is deformed allowing the safe discharging of the nitrogen gas spring.
