Tightening Torque: 7Nm
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.
