A haptic actuator may include a housing having opposing ends and opposing sides extending therebetween. The haptic actuator may also include at least one coil carried by the housing and a field member having opposing ends and opposing sides extending therebetween. The haptic actuator may also include a respective flexure coupling each end of the field member to an adjacent end of the housing so that the field member is reciprocally movable within the housing responsive to the at least one coil over an operating range and while maintaining a respective sidewall clearance between each side of the field member and an adjacent side of the housing. At least one sidewall clearance restricting feature may be configured to restrict the sidewall clearance when the field member moves beyond the operating range when subject to mechanical shock.
