12.6.2 Greasing Method
For the ball screws of RA2AC and RA2AR, apply grease directly. For those equipped with spiral
cover, follow the instruction below to apply grease.
[1] Turn off the power and check the surface of the spiral cover for shavings, powder dust, etc. Use
a waste cloth, etc., to wipe off shavings, powder dust, if any.
[2] Extend the rod and pull the narrower end of the spiral cover toward the wider end (in the
direction of the arrow) to expose the screw shaft. If the lead is too small and the rod does not
move, insert a slotted screwdriver, etc., into the cutout groove provided in the shaft on the rear
side and turn. [Refer to 10.2, “How to Move Rod by Hand”.]
Spiral cover
[3] Wipe off grease attached to the Lead screw or ball screw and then apply the specified grease.
[4] Install the spiral cover in the original condition and move the rod to spread the grease evenly.
Caution : In case the grease got into your eye, immediately go to see the doctor to get an
appropriate care.
After finishing the grease supply work, wash your hands carefully with water and
soap to rinse the grease off.
