A suspension assembly has a flexure limiter and an actuator of a disk drive adopting the flexure limiter. The suspension assembly elastically biases a slider toward a surface of a disk, in which a read/write head is mounted on the slider. In the suspension assembly, a load beam is coupled to an end portion of a swing arm of the actuator and has sidewalls bent along both outside edges thereof. A flexure supports the slider and has a rear end portion fixed to a disk facing surface of the load beam and a front end portion extended toward a front end portion of the load beam. A flexure limiter is bent from the front end portion of the flexure toward the load beam to face a surface opposite to the disk facing surface of the load beam, thus limiting a range of pitching and rolling movements of the flexure.
