10. Maintenance and Inspection

10.4 Internal Check (Slider Type)
[1] With the SA6C and SA7C, the screw cover
and side covers can be removed using a hex
wrench with 1.5 mm width across flats.
x The front and rear brackets are supporting the
ball screw, so do not disassemble these
brackets.
x Precision instrument is assembled into the
motor cover, so do not disassemble the motor
cover.
[2] Visually check the internal condition. Check for
intrusion of dust and other foreign object, and
also check the lubrication condition. Even
when the grease is brown, the sliding surface
is lubricated properly if the surface looks wet
and glowing.
Warning: The encoder phase is adjusted precisely to enable detection of rotation angle and home
signal. Never touch the encoder, since it may cause a breakdown.
[3] If the grease is contaminated with dust and not glowing, or if the grease has been consumed over a long period of
use, apply grease after cleaning the respective parts.
[4] When the inspection/maintenance is complete, install the side covers, stainless sheet and slider cover by
reversing the procedure in step [1] above. The tightening torque should be around the level applicable for cross-
recessed screws.
