11.7 How to Add Grease to the Ball Screw
11.7.1 Applicable Grease
The following lithium grease has been applied prior to shipment.
Kyodo Yushi Multemp LRL 3
This grease has excellent properties including low heat generation and is suitable for ball screws.
Warning
Never use fluorine grease. If fluorine grease is mixed with lithium grease, lithium grease will lose its
intended lubrication property and the machine may be damaged.
11.7.2 How to Apply Grease
Clean the ball screw before applying grease. Apply grease by hand, and then move the slider back and
forth to let grease spread evenly. Finally, wipe off excess grease that has overflowed from the nut.
Apply grease on the ball screw.
Move the slider. If the actuator is equipped
with a brake, release the brake.
Caution: Adding too much grease may increase the agitation resistance and cause the ball screw
to generate heat easily or the excess grease attached to the ball screw may scatter and
dirty the surrounding area. Be sure to wipe off excess grease.
