Products of the TUBUS-serieswill work at temperaturesof -40 °Fup to120 °F and are resistant togrease, oil, petroleum fluids, microbe and chemical attack and seawater. They alsohavegoodUV andozone resistance. The very longservice life of up toonemillion cycles, the compact size and the lowunitweight differentiate the TUBUSbumpers from all other types of elastomer dampingproducts. If you are looking for aneconomicdamping solutionwhere the loaddoes not need tobedecelerated to anexact datumposition and youdonot need100% absorptionof the impact energy then TUBUSbumpers are a real alternative tohydraulic endpositiondamping. They are thepreferred solution for end stopdampers in robotic systems, highbaywarehouse systems and all similar automatedplant andmachinery. For the crane industrywemanufacture special highcapacitycrane buffers that have an ideal deceleration characteristicwithhigh return force for this typeof application andenergy capacities from3,983 in-lbs to157,632 in-lbs. Thismeans you canhave a TUBUS cranebuffer capableof providingup to202,329 lbs of braking force in apackageonly weighing2.20 lbs and absorbingup to50%of theenergy. ACE TUBUSbumpers arehighperformancedampingproducts made from a special Co-Polyester Elastomer. They have ahigh energy absorbing capacity comparedwithothermaterials. TheTUBUS-seriescomprises7main typeswithover 140 individual models. Theexcellent damping characteristics are achieved as a result of the special elastomermaterial and theworldwidepatented con- structiondesign. This enables us to change the characteristics of theelastomermaterial so that individual anddistinct damping curves arepossible. TUBUSbumpers offer a considerableperformance advantage when compared toothermaterials such as rubber, urethanes (PUR) and steel springs. A further advantage compared toother dampingproducts is the operating lifeexpectancy–up to twenty times longer thanurethanedampers, up to ten times longer than rubber dampersandup tofive times longer thansteel spring dampers. The innovative TUBUSbumpers absorbenergywhileexhibiting the followingdamping characteristics: Model typeTA: Degressive characteristicwithmax. energy absorption (coloured area) withmin. stroke. Energy absorption: 58% to73%. Model typeTS: Almost linear characteristicwith low reaction forceover a short operating stroke. Energy absorption: 35% to64%. TR/TR-H/TR-L: Progressive characteristicwithgradually increasing reaction forceover a long stroke. Energy absorption TR : 25% to45% Energy absorption TR-H : 39% to62% Energy absorption TR-L : 26% to41% Besides the standardproduct rangeof the TUBUS-series there are also a largenumber of special products availableupon request for customer- specific applications.
