When a profile damper fits. TUBUS dampers are the economical, long-life answer when you need to absorb energy and protect a machine but don't require deceleration to a precise end point. As solid elastomer with no fluid or moving parts, they shrug off harsh environments — resistant to seawater, chemicals, microbes, UV, and ozone — and last up to 20× longer than urethane, 10× longer than rubber, and 5× longer than steel-spring dampers, with service life reaching a million cycles.
Pick the family by damping curve. TA (axial) is the compact powerhouse, absorbing most of the energy early in a short stroke (58–73% energy absorption), from about 18 to 17,825 in-lbs/cycle. TS (axial soft) gives an almost-linear curve with low reaction force for gentle, low-stress stops. TR (radial) trades height for a long, soft braking action, with TR-H adding a harder compound for higher energy and TR-HD a solid heavy-duty body reaching over 100,000 in-lbs/cycle for impact and collision protection. All mount in minutes with the supplied screw and operate from -40°F to 194°F.
Where they're used. End-position damping on linear axes and slides, tool machines, hydraulic and pneumatic equipment, handling modules, swivel units, and conveyor and crane systems — including demanding marine and outdoor settings where the corrosion resistance pays off.
When you need metered, repeatable deceleration to an exact point rather than elastomer damping, step up to our industrial shock absorbers; to spread impact or vibration across a larger surface, see our damping pads.
