Profile Dampers
TR143-86L-1

Powerhouse in long body length

Radial Damping, Long Version
Energy capacity 600.0 Nm/cycle
Stroke max. 86 mm

Especially for applications with long and soft deceleration: The radial tube dampers TR-L from the ACE TUBUS-Series are maintenance-free, ready-to-install elements made of co-polyester elastomer.

Their radial load offers designers a very long and soft deceleration with a progressive reduction in energy at the end of the stroke. The TR-L range has been specially developed for a maximum stroke with a minimum height and a range of 7.2 Nm to 10,780 Nm. The absorption capacity is dependent on the length of the selected tube damper. These models are available in sizes between Ø 29 mm and Ø 188 mm.

Application Examples

Profile Dampers - TUBUS TR-L

Saltwater-resistant impact protection for lifeboats

When launching lifeboats, it is theoretically conceivable that there will be contact between the ship and lifeboat. Launching appliances with protective bodies are fitted in order that the lifeboat is not damaged. Since TUBUS TR-L profile dampers ...

Application Areas

offshore industry
agricultural machinery
impact panels
conveyor systems
stacking units
shipbuilding
shovels or articulated joints for construction machinery
transport roads
loading and lifting equipment

The TUBUS TR-L is used where impact or collision protection is necessary along a straight line e.g. on shovels in mining equipment, loading and lifting devices, dock systems in shipbuilding or luggage and transport belts.
