* Actuator is designed for cyclic use at rated torque: rated at maximum differential
pressure at 21 MPa (3000 psi).
† P and M are interdependent: if P is at maximum, M must be zero; if P = 75% of
maximum, M may be up to 25% of its maximum value.
‡ If these values are to be exceeded, additional internal or external cushions are
required, contact MTS.
§ w = rotational velocity in rad/sec and J or I = rotational inertia in lbm-in.

including inertias from rotary actuator, flange, flexure, and 1/2 of test specimen (lbm =
pounds mass).
