Abrégé

An actuator including a housing, an actuator rod and a snubber assembly. The actuator has an axis, the housing has a first end and an aperture positioned at the first end of the housing, and the actuator rod extends through the aperture along the axis of the actuator.The snubber assembly is mounted at the first end of the housing, and includes one or more energy absorbing devices. The snubber assembly is positioned on the housing such that an axis of each of the one or more energy absorbing devices is offset relative to the axis of the actuator.The snubber assembly is configured such that the one or more energy absorbing devices provide bidirectional end-of-stroke damping.
