Radial Damping
Energy capacity 34.5 Nm/cycle
Stroke max. 46 mm

For long, soft braking action: The Radial damping forces in this model from the ACE TUBUS-Series provides the TR range. These maintenance-free, ready-to-install elements are made of co-polyester elastomer, which only heats up slightly during operation and therefore provides consistent damping.

The radial loading enables a very long and soft deceleration with progressive energy reduction at the end of the stroke. The TR product family has been specially designed for maximum stroke with a minimum height, producing an energy absorption per stroke extending from 1.2 Nm to 146 Nm. The dampers are available in compact formats of Ø 29 mm to Ø 100 mm and are supplied with a special screw for simple, quick assembly.

Application Examples

TUBUS-TR End position absorption on the hydraulic drive
TUBUS-TR End position absorption on the hydraulic drive
TUBUS profile dampers safeguard hydraulic cylinders. In a testing facility for vehicle tanks, the test specimens are pulled out of the water with a support arm. A hydraulic cylinder carries out the swinging movement and is attenuated in the end position by two TUBUS TR85-50. Even if this work could be taken over by other absorber solutions, the energy balance clearly speaks for the benefits of ...

TUBUS-TR turns shipping crates into sedans
High-quality audio and video technology literally have a high turnover rate in lorries during transport. Well-cushioned shipping crates are necessary in order that the high-quality equipment is not damaged and that work can begin immediately at any location in the world. To eliminate, in particular, the damaging vertical impetuses due to impacts and falling, the BLOW UP Videoproduktion company ...
TUBUS-TR e-Scooter
TUBUS-TR e-Scooter
TUBUS profile dampers make driving an e-scooter a real experience. The footboard of an electric scooter should be dampened to enable the driver to experience a comfortable ride even over potholes and other bumpy surfaces. Ideally, the characteristic line should be furnished with a soft increase in force over a long stroke. The elegant look of the scooter as well as the folding mechanism ...
