ABSTRACT:
A guide (30) for surrounding and sealing a rod (26) in the end of a hydraulic cylinder (12) including a piston (24) slidably disposed in the cylinder (12) and attached to the end of the rod (26) and a method for manufacturing the guide (30). The guide (30) includes an inner guide bore (38) with dovetail shaped channels (40) extending annularly about the guide bore (38) and an organic polymeric bearing material (42) disposed in the guide bore (38) in mechanically interlocking engagement with the dovetail channel in the radial direction to exert a radial retaining force from the channel (40) to the bearing material (42) to establish a force fit in the radial direction between the channel (40) and the bearing material (42) placing the guide (30) in a mold (44, 46) defining a cylindrical cavity extending about the guide bore (38) and between the end faces (32) of the guide (30). The guide is manufactured by filling a cylindrical cavity adjacent the guide bore (38) with an organic polymeric bearing material (42) and, after curing the bearing material (42), machining a rod engaging surface (54) into the interior of the bearing material (42), the bearing material (42) being machined in reference to and to a closer tolerance than the machined surface (34) on the exterior of the guide (30).
