Compact powerhouse in solid material

Radial Damping, Heavy Duty Version
Energy capacity 405 Nm/Cycle to 11,840 Nm/Cycle
Maximum stroke 12 mm to 44 mm

Impact and collision protection: The TR-HD profile dampers are stressed in the same way as the basic model TR but offer a higher force and energy absorption with a shorter damping distance thanks to the solid design. Different damping characteristic curves can be achieved with two different co-polyester elastomer hardness levels. The slightly oval (bi-concave) shape also ensures a softer force intake.

This product family absorbs a lot of energy despite the low height: a range of 405 Nm to 11,840 Nm is progressively covered by strokes of 12 mm to 44 mm. With two screws, included in the delivery, the damper can be easily and quickly fixed both horizontally or vertically. The drill hole distance is adapted if required.

These dampers are used in agricultural technology and on shovels or break joints on construction machines as well as on loading and lifting or similar equipment.
