Swageable base plate with gram load offset and adjustment feature

摘要

A base plate with a hub and a flange having a clamping region in a horizontal plane and an extended flange portion. The clamping region surrounds and is contiguous with the hub. The extended flange portion has a tip region at a distal end thereof. The extended flange portion is contiguous with the clamping region and has a concentrated strain region between the clamping region and the tip region. The concentrated strain region is capable of being distorted for gram-load adjustment. The tip region may be inclined at an angle of not more than 10 degrees from the horizontal plane. For assembly in a head suspension, the tip region is welded to a load beam. The gram-load on the load beam is measured with reference to a standard and the concentrated strain region is distorted for gram-load adjustment to the standard.
