Force Rating:  The linear force produced by the actuator at continuous motor torque.

Max Velocity:  The linear velocity that the actuator will achieve at rated motor rpm.

Continuous Motor Torque:  Torque produced by the motor at rated continuous current.

Maximum Static Load:  The mechanical load limit of the actuator if re-circulated oil or other cooling method is used to allow higher than rated torque from the motor.

Armature Inertia:  The rotary inertia of the armature of the EL Series actuators.  For calculation purposes, this value includes the screw inertia in an EL Series actuator.  Tolerance for inertia is +/-5%.

Dynamic Load Rating:  A design constant used in calculating the estimated travel life of the roller screw.  The cubic mean load is the load at which the device will perform one million revolutions.
