The preload adjustment is accomplished through the slider's
center eccentric roller. After inserting the slider into the rail, the
preload is set by adjusting the center roller against the opposite
raceway using 2 Allen keys. This adjustment must be made before mounting
since 1 Allen key must pass through a rail mounting hole into the axel
of the center roller. ( see illustration). During adjustment of the
eccentric roller, it is necessary to keep the mounting screw ( in the
slider body ) a tight until contact with the opposing raceway. After
light contact of the eccentric roller, the Allen key behind the rail
will be held firm while the mounting screw is tightened. Move the slider
along the whole rail to ensure smooth movement without clearance. If the
slider is found to be too tight or has some clearance in places,
readjust to suit.
