1. A tangential linear flexure bearing having a diaphragm, and at least one rim spacer and at least one hub spacer, said diaphragm having a hub with a predetermined number of equiangularly disposed radially extending hub extensions each having a distal end, having a same predetermined number of respective hub arms extending tangentially from said distal ends of said hub extensions, having a same predetermined number of tangentially disposed flexure blades each having a uniform width along a length, and having a circular rim having a same predetermined number of rim arms equiangular disposed about said rim and extending tangentially from said circular rim, said flexure blades have distal ends tangentially extending from respective rim arms and have proximal ends respectively tangentially extending from said hub arms, said rim spacer identical in shape to said circular rim, said hub spacer identical in shape to said hub, said rim spacer and hub spacer being rigidly attached to said diaphragm in alignment of to said hub and said rim, wherein the improvement comprises,said proximal ends of said flexure blades as defined by said respective hub arms forms a negative angle from respective radial lines radially extending from a center point of said diaphragm and orthogonal to said length of said flexure blades, said distal ends of said flexure blades as defined by said respective rim arms forms a positive angle from said respective radial lines, said negative angle and said positive angle being equal but opposite to each other, and said distal ends and said proximal ends equally displaced and centered from said respective radial lines and defining a trapezoidal shape of said flexure blades.
