Abstract
A load beam of a suspension assembly has one or more longitudinal channels in the rigid region between the side edges. The load beam blank (from which the load beam itself is constructed) has a relief means, such as a channel-compensating gap extending through the actuator mounting region from the proximal end to provide additional width of sheet material to the rigid region of the load beam blank and to enable the formation of these longitudinal channels. A method for manufacturing a load beam of a suspension assembly from a generally planar sheet of resilient spring material is described. A load beam blank is shaped to include an actuator mounting region on the distal end, and a rigid region between the actuator mounting region and the distal end. A relief means, such as a channel-compensating gap extends through the actuator mounting region from the proximal end. At least one channel is constructed in the rigid region. The channel preferably extends between the gap and the distal end of the load beam and thereby reduces the width of the gap in the blank.
