Unparalleled Performance
Exceptional fidelity over the full range of motion reduces distortion
Full Product Information
High-quality Actuators for Testing Applications
MTS DuraGlide 244 Hydraulic Actuators are double-ended, fatigue-rated and designed with proprietary materials that minimize friction, while maximizing reliability, wear resistance and ease of maintenance. They are hydraulically-powered pistons that can extend or retract (double-acting) to provide displacement or force into a test article or structure. These actuators are used worldwide in a variety of demanding applications from vehicle dynamics and structural fatigue to component testing, and are recommended for dynamic, static and fatigue applications.
Long Performance Life
MTS DuraGlide 244 Actuators are manufactured with an environmentally friendly, RoHS-compliant, rod surface coating and proprietary surface-finishing processes that set the industry standard for durability, longevity and performance. The MTS SureCoat Rod Finishing Technology increases actuator life expectancy by 10x over actuators with conventionally chrome-plated rods.
Testing Speed and Fidelity
The MTS SureCoat Rod Finishing Technology reduces rod banding by 10x as well. Without having to adjust for rod banding, test engineers can keep the optimal zero stroke position and decrease the need for crosshead position changes that can disturb load train alignment. The ability to retain the zero stroke position over hundreds of millions of punishing cycles, will give more consistent testing results and speed the testing process. In addition, higher fidelity actuators reduce the distortion that can lead to measurement uncertainty and save time by producing statistically significant results in fewer batches.
Energy Efficiency
MTS actuators are engineered to provide maximum performance while introducing the minimal amount of friction into the test system, reducing internal flow losses and heat produced, thus requiring less energy to operate. Minimizing drain flow eliminates the need to use scavenge pumps that negatively aerate oil, further reducing the required energy budget. When these actuators are used with other energy-saving MTS hydraulic products, the cost savings multiply.
Thermal spray-coated piston rods that have 10x greater service life than hard chrome-plated rods
Proprietary MTS seal and bearing designs and surfacecoating processes set the industry standard for durability, longevity and performance
Double-ended, fatigue-rated design (piston rod extends from both sides) combines balanced dynamic performance and robust side-load tolerance to maximize data fidelity
High-capacity, non-metallic, ultra-low friction bearings bonded directly to the end caps offer high side-load tolerance and resistance to failure from galling and seizure
Cushions protect the actuator from the effects of high-speed and high-mass forces, and prevent the piston from contacting the end caps.
