ABSTRACT:
A cylinder-stem assembly to floating platform, gap controlling interface guide. A longitudinal wear strip and mating guide are positioned at an angle relative to a tangent to the nominally round exterior cylinder of the cylinder. Cylinder guides may be provided at more than a single elevation. The corners of the contacting surfaces of the wear strips may be rounded to reduce the risk of galling and to avoid any obvious point or line loading. During assembly, the cylinder-stem assembly is rotated after insertion into its slot in the floating platform. The rotation centers the cylinder and also may be used to control the magnitude of the gap or an interference fit.
