86 Issue7.2014 Specifications subject to change 86 One-Piece ProfileBody MountingScrew TUBUS-SeriesTypeTR-LBumper Radial Damping (LongVersion) The radial tubebumper typeTR-L from the innovativeACE TUBUS series is amainte- nance-free, self-containeddampingproduct made from a special Co-Polyester Elastomer. The radial deformationof theTRseriesprovides a very long and soft decelerationwith apro- gressiveenergy absorption towards theendof stroke. Theexcellent temperature characteris- ticof thematerial provides consistent damping performanceover a temperatureof -40 °F to 120 °F. The tubebumper hasbeen specially developed for applications that require very low reaction forces. The actual forcegenerated depends upon the lengthof the tubebumper chosen. The TUBUS TR-L type is suitable for a wide rangeof applications that requireprotec- tion from shock or impact anywhere along a straight line. Typical applications include miningequipment, dockyardhandlingequip- ment andonbaggagehandling and conveyor systems. The TR-L series havebeendeveloped toprovide maximumstroke in the minimum mountingspace in the capacity range from 63.7 in-lbs up to95,411 in-lbs. Lifeexpectancy is extremely high; up to twenty times longer thanurethanedampers, up to ten times longer than rubber bumpers andup to five times longer than steel springs.
