11.5 Lubricating the Ball Screw
11.5-1 Ball Screw Grease
When we ship the units, we use the following grease which is specifically for ball screws.
Kyodo Yushi Ball temp LRL3
This product is well suited for ball screws and has excellent properties such as low heat generation. We recom-
mend it when doing maintenance work but for consistency it is all right to use the same grease used for the guide.
There is no problem using the two together since both are lithium type grease.
11.5-2 Lubrication
Clean the screw, then apply grease with your finger and spread it out by moving the slider back and forth.
After this, wipe off any excess grease leaking from the nut. Application is done this way because if too much
grease is applied, the agitation resistance increases and the ball screw generates heat more easily. Also, when
the ball screw rotates, excess grease is splattered on the surrounding areas.
!!
WARNING
!!
Never use any fluorine based grease. When mixed with a lithium based
grease, not only does the grease lose its performance but it can actually dam-
age the actuator.
