10. Maintenance/Inspection
10.5 Interior Check
Turn off the power, remove the stainless sheet and visually inspect the interior.
For the interior inspection, check the following items.
Actuator Loosening of actuator mounting bolts, etc.
Guide Lubrication condition, soiling
Joint Lubrication condition, soiling
Visually check the condition of the interior. Specifically, see if there is any dust or foreign object inside the
actuator and also check the condition of lubrication.
Even if the grease has turned brown, lubrication is fine as long as the traveling surface appears shiny.
If the grease becomes dirty and dull due to dust, or if the grease has worn away due to an extended
operating time, lubricate the parts after cleaning them.
The procedure for checking the interior is explained below.
(1) Move the slider to the motor end.
(2) Remove the screws from the sheet retainer using an Allen wrench of 2.5 mm across flats.
(3) Turn up the sheet and check the interior.
(4) When you are done, assemble the parts by following the same procedure in reverse.
Caution: y Do not disassemble the front cover because the ball screw is supported by the front cover. If
a proper adjustment of the front cover is lost, the shaft center may become offset and the
traveling resistance may increase or life of each part may become shorter, or abnormal
noises may generate.
y Be careful not to forcibly bend or accidentally scratch the stainless sheet when checking the
interior.
Do not pull the sheet or otherwise cause its state after initial installation to change. If the
installed state of the sheet is changed, the sheet may shift to one side or its life may be
reduced. If you have accidentally caused such change, contact IAI’s Sales Engineering.
Also remember to wear gloves or use other means to protect your hands from cuts at the end
face of the stainless sheet.
