Compact size and strong force absorption

Axial Damping
Energy capacity 17.7 in-lbs/Cycle to 17,825 in-lbs/Cycle
Maximum stroke 0.20 in to 1.89 in

Very efficient energy guzzlers: The TA profile dampers from the ACE TUBUS-Series are maintenance-free and ready to install. They're made of co-polyester elastomer; a material that only heats up slightly and ensures consistent damping. The TA models absorbs most of the energy at the start of the stroke. 

The TA family has been specially developed for maximum energy absorption within a range of 18 in-lbs to 26,119 in-lbs. (2 Nm to 2,951 Nm). These dampers have a minimum height is thanks to the space-saving shape, with Ø 0.47" to Ø 4.57" (Ø 12 mm to Ø 116 mm). The dampers can be very easily and quickly installed with the provided special screw.

These compact, cost-effective dampers are ideal as end position dampers in linear axes, in toolmaking and tool machines, in hydraulic and pneumatic equipment, handling equipment and other applications.
