10.7 Greasing the Ball Screw (Slider Type)
(1) Applicable grease
The following special grease is applied to the ball screw prior to shipment:
Kyodo Yushi Multemp LRL3
This grease generates less heat and has other excellent properties suitable for ball screws. For equivalent grease
products, refer to the brands specified for the guide (lithium grease).
Note: Never use fluorine grease. If fluorine grease is mixed with lithium grease, the grease function will drop
and it causes damage to the mechanism.
(2) Greasing method
After cleaning the ball screw, apply grease and
stroke the slider to let the grease spread evenly.
As the final step, wipe off excess grease from the
ball screw.
This is because excessive grease will cause the
agitation resistance to increase and allow the ball
screw to generate heat easily. Wiping off excess
grease will also prevent extra grease on the ball
screw from flying off and staining the surrounding
area as the screw turns.
* With the ERC2, the speed will vary depending
on the load. Be careful not to grease the ball
screw excessively.
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.
