TUBUS TR

Compact size and soft deceleration

Radial Damping
Energy capacity 10.6 in-lbs/Cycle to 1,018 in-lbs/Cycle
Maximum stroke 0.67 in to 2.36 in

For long, soft braking action: The TUBUS TR series deliver linear damping forces. 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-Series has been specially designed for maximum stroke with a minimum height, producing energy absorption per stroke extending from 10.6 in-lbs to 1,292 in-lbs. (1.2 Nm to 146 Nm). The dampers are available in compact formats of Ø 1.14" to Ø 3.94"(Ø 29 mm to Ø 100 mm) and are supplied with a special screw for simple, quick assembly.

The TUBUS TR products are suitable as end position dampers in linear axes, in tool making and tool machines, in hydraulic and pneumatic equipment, handling equipment and other applications.

Application Examples

TUBUS-TR End position absorption on the hydraulic drive
TUBUS-TR End position absorption on the hydraulic drive
TUBUS bumpers 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 the ...
TUBUS-TR  e-Scooter
TUBUS-TR e-Scooter
TUBUS bumpers 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 designed to ...
