Roehrig Engineering has established a reputation within the motorsports industry as the recognized leader in shock and spring rate test equipment.
Now, after having installed more than 1,000 systems worldwide, Roehrig Engineering is able to provide this superior technology to other markets, including durability and fatigue, materials characterization, consumer goods, as well as general automotive component manufacturers.

In 2014, MTS significantly expanded its damper and road simulation testing portfolio with the acquisition of Roehrig Engineering, Inc. of Lexington, North Carolina. With the addition of Roehrig electric actuation technologies, MTS now offers the industry’s broadest selection of damper test solutions for garage, track, proving ground and laboratory, and is well-positioned to address growing industry demands for cleaner, quieter and more efficient damper test solutions. Clean and quiet electric actuation also augments the MTS tire-coupled road simulator offering, enabling more effective and efficient production quality testing.

MTS Roehrig SYD Damper (Crank Dyno) Test Systems
A complete family of electro-mechanical crank dynos for performing single-specimen sinusoidal damper testing.

the energy conversion is direct, it is not wasted in motor and pump inefficiencies, hydraulic line losses, seal friction and heat removal.

without the need for hydraulics, issues such as oil cleanliness, hazardous waste disposal, spill containment and specimen contamination are no concern.

our systems operate independent of issues such as fluid contamination, temperature, servo valve wear, hydraulic accumulators so results are more repeatable.

with fewer moving parts, maintenance costs are lower, spare parts are kept to a minimum, downtime is reduced and troubleshooting is simplified.

Our dynos are also currently being used by the Indonesian railway depots and workshops in multiple locations throughout Java and Sumatra.
