Abstract: A linear actuator comprising a shaft and a nut that translates within a linear range of motion in response to relative rotation between the nut and shaft, a stop positioned at a travel limiting position and having an inner portion connected to the shaft, a radially compliant outer portion axially overlapping the inner portion and configured to rotate relative to the inner portion, and a cam roller portion disposed radially between the inner and outer portions and configured to move relative to a neutral orientation in response to relative rotation between the inner and outer portions, and the outer portion configured to radially bias the cam roller portion towards the neutral orientation; wherein rotation of the outer portion caused by the nut rotating into the outer portion provides an outward radial load at the cam roller portion on the outer portion that is absorbed by the outer portion.
