Abstract
A bearing for use between an outer member and an inner member that is movable relative to the outer member. The bearing includes a generally cylindrical plastic body having a plurality of undulations that form gradual radially inward and radially outward waves relative to a circular path.
Claims16
A bearing for use between an outer member and an inner member that is movable relative to the outer member, comprising:
- a generally cylindrical plastic body having a plurality of generally sinusoidal undulations that form radially inward and radially outward waves relative to a circular path.
A bearing for use between an outer member and an inner member that is movable relative to the outer member, comprising:
- a generally cylindrical plastic body having a plurality of undulations that form radially inward and radially outward waves relative to a circular path;
- and
- wherein the radially inward and radially outward waves of the plurality of undulations each have a peak surface that is non-parallel to a center axis of the generally cylindrical plastic body.
A bearing for use between an outer member and an inner member that is movable relative to the outer member, comprising:
- a generally cylindrical plastic body having a plurality of undulations that form radially inward and radially outward waves relative to a circular path;
- wherein the plurality of undulations include adjacent undulations on an interior surface having a differing alternating pattern;
- and
- wherein the adjacent undulations of the interior surface include grooves that get narrower from one axial end to another.
A bearing for use between an outer member and an inner member that is movable relative to the outer member, comprising:
- a cylindrical plastic body having an inner diameter surface with a plurality of circumferentially spaced grooves;
- and
- wherein the plurality of circumferentially spaced grooves widen from one axial end of the cylindrical plastic body to an opposite axial end of the cylindrical plastic body.
A shaft guide system, comprising:
- a metal outer member;
- a metal inner member that is movable relative to the metal outer member;
- and
- a generally cylindrical plastic body having a plurality of generally sinusoidal undulations that form radially inward and radially outward waves relative to a circular path.
