Abstract

A suspension strut comprises inner and outer tubes and incorporates an end closure constituted by a moulded plastic insert containing a sleeve bearing in the form of a metal bush, the insert being a press fit into the outer tube of the strut and the press fit region of the insert including a portion adapted to engage with and locate in a radial direction the inner tube of the strut, together with at least two circumferential ribs which extend radially from the insert to engage the inner surface of the outer tube, the material of said ribs being in compression, with said ribs being spaced apart axially of the strut to confer a degree of resilience onto the assembly and a fluid seal being provided at or adjacent the outer face of the end closure to minimize fluid losses from the strut along the relatively movable rod thereof.
