Inspection items Maintenance work
Backlash/play or wear debris found?
The ball screw guide may be damaged.
Contact IAI.
Has foreign matter penetrated inside?
Remove the foreign matter, clean, and inspect
the interior for any damage.
Is the ball screw or guide grease not
lubricating well?
(Even if the grease is brown, lubrication is
adequate if the running surface is shiny )
Wipe away the old grease, then replenish with
new grease.
Is dust or foreign matter adhered to the
ball screw or guide?
Replenish with new grease after cleaning.
Internal inspection method
1) Loosen the screws on the side cover and detach the side cover.
2) Check inside.
3) After finishing the inspection, assemble back in the reverse order. If you touch the
edge of the stainless steel sheet in the attaching the side cover process, the sheet
may get damaged or wavy which result in shortening life or earlier wear-out.
To avoid touching the edge of the sheet, insert a spacer (approximately 0.1 to 0.2mm)
between the sheet and cover to push up the sheet, and then push in the cover.
When affixing the side cover, tighten the screws with the tightening torque described
below.

4) Make sure that the slider and the side cover do not interfere, moving the slider
backwards and forwards between the strokes.
