Abstract

A geometric shaped side bearing pad includes a top and a surface extending an angle θ towards the top, wherein the bearing pad has a geometric shape and a non-linear spring rate which levels out a reaction force without buckling. The surface of the bearing pad can have two sides or four sides, can have spacing within the surface, or can be solid. The angle θ can be within the range of about 20 degrees and 85 degrees, and may preferably be within the range of about 30 degrees and 45 degrees to achieve non-linear load/deflection. The top of the bearing pad can have a slot defined therethrough to accommodate a protrusion in a fixture to engage the bearing pad. The bearing pad can provide a friction contact with an object and enables lateral force transfer to the bearing pad, thereby providing lateral stiffness.
