Profile Dampers

Compact size with soft deceleration and high energy absorption

Radial Damping, Hard Version
Energy capacity 721 in-lbs/cycle
Stroke max. 1.65 inch

Harder mixture of materials for higher energy absorption: The maintenance-free and ready-to-install TR-H profile dampers, are stressed radially in the same way as the basic TR model. With almost the same dimensions, they also decelerate with a very long and soft action. The harder co-polyester elastomer mixture leads to significantly high energy absorption of 23.9 in-lbs to 3,779 in-lbs (2.7 Nm to 427 Nm) in these models. The supplied special screw makes them easy to mount.

The TR-H product family is space-saving with dimensions of Ø 1.18"" to Ø 4.02"" (Ø 30 mm to Ø 102 mm). It complements the TUBUS range between the progressive TR and almost linear TS models. Users are therefore provided with a full range of deceleration curves within the ACE TUBUS family.
