Caution: Make sure the load installed on the actuator is not longer than the allowable overhang load length
(L). If the load is longer than L, vibration may occur or the settling time may increase depending on
the position of center of gravity position or weight of the work part.
If a moment exceeding the allowable moment is applied, not only the life of the guide will become
shorter but vibration or longer settling time may also result.
