Rotary Actuators

Designed for heavy duty torsion generation, MTS rotary actuators offer precise control in a closed-loop servohydraulic test environment. These robust actuators are ideal for fatigue and durability testing of drivetrain components and other materials.

Key Product Features

Long Product Life

Roller bearings accommodate high radial loads while minimizing friction to extend product life


Chamber & rotor design eliminates backlash during torque reversals

Durable / Reliable

Fatigue-rated designs, built to exceed their rated loads for millions of cycles


Equal working area for both rotational directions provides precise control

Model Comparison

Series 215

  • Dynamic torque ratings: 226 N-m - 11,300 N-m (2000 lbf-in - 100,000 lbf-in)
  • Ideal for:
    • Testing materials, axles, couplings, driveshafts, and other rotational components

Series 216

  • Dynamic torque ratings: 22,597 N-m - 82,479 N-m (200,000 lbf-in - 730,000 lbf-in)
  • Provides more torque than the Series 215 rotary actuators, while maintaining incredible control fidelity
  • Ideal for:
    • Testing materials, axles, couplings, driveshafts, and other rotational components


Model 217

  • Custom-designed rotary actuators available
