12.5 Adding Grease
(1) Applicable Grease
Our guides use urea grease that offers excellent low-dust-raising property, stable torque characteristics,
excellent lubrication performance, and rust-preventive effect similar to lithium grease. The following grease
has been applied to the guides of your actuator prior to shipment from IAI.

Ball screw Daphne Eponex Grease No.2 Kuroda C grease
Warning: x If your actuator is of cleanroom type, use low-dust-raising grease. If standard grease is used,
dust may be raised.
x Never use fluorine or lithium grease. If fluorine or lithium grease is mixed with urea grease,
the lubrication performance normally expected from urea grease may be lost and
consequently the mechanical parts may be damaged or cleanliness may drop.
(2) How to add grease
Adding grease to the guides and ball screw
Grease nipples are provided on both sides of the slider. Add grease to the guides and ball screw through these
grease nipples.
The grease nipples on the right side as viewed from the motor are used to add grease to the guide on the right
side as well as the ball screw.
The grease nipples on the left side as viewed from the motor are used to add grease to the guide on the left
side as well as the ball screw.
(Grease can be added to the ball screw from the grease nipple on either side.)
[1] Remove the grease nipple caps on the slider cover.
[2] Supply grease from the left and right grease nipples three to four times using a grease gun.
The table below lists the effective charge volumes of grease.
