1. A bearing system for a scissor lift, the system comprising:
a sliding shuttle having x, y, and z coordinate planes,
wherein the shuttle has a backplate, and
the shuttle has a geometry protruding from the backplate in the z-direction, an area of the protruding geometry in the x-y plane being less than that of the backplate;
a first biased member having geometry complimentary to a top of the protruding geometry,
a second biased member having geometry complimentary to a bottom of the protruding geometry,
wherein:
the first biased member is removably attached to the top of the protruding geometry at a first end and a second end;
the second biased member is removably attached to the bottom of the protruding geometry at a first end and a second end; and
the protruding geometry comprises angles greater than 90°.
