Patent ID: 6968931

Claim:
A suspended shock absorber having a bearing arrangement and coil spring, the shock absorber having only first and second tubes in which the first tube is telescopically slidable in the second tube along a longitudinal axis, a piston rod mounted in the second tube and a piston on said piston rod in slidable contact in said first tube for reciprocal travel therein, said bearing arrangement comprising: first and second bearings respectively engaging said first and second tubes for guiding movement of said first tube within said second tube, said first bearing being mounted on a support tube stub secured around an outer surface of said first tube, said first bearing including a plurality of first rollers having outer surfaces in contact with the outer surface of said first tubes said first rollers having concave outer surfaces corresponding to the outer surface of said first tube, said concave surfaces being in rolling contact with the outer surface of said first tube, said first rollers being rotatable in said first bearing around axes which are perpendicular to said longitudinal axis along which the first tube is movable, said second bearing being mounted on a support tube stub at a lower end of the first tube and includes a plurality of second rollers in contact with an inner surface of said second tube, said second rollers having convex outer surfaces corresponding to the inner surface of said second tube, said convex surfaces being in rolling contact with said inner surface of said second tube, said second rollers being rotatable in said second bearing around axes which are perpendicular to said longitudinal axis along which the first tube is movable; and wherein the first and second tubes are circular in cross-section, the convex outer surfaces of the second rollers of the second bearing are adapted to the inner diameter of the second tube and the concave outer surfaces of the first rollers of the first bearing are adapted to the outer diameter of the first tube.
