4.6.2 How to Apply Grease
1) Remove the attachment screws (at arrows) on the side cover to detach the side cover on one
side.
Screws: M2.5, M3 (BA4/BA4U), M3 (BA6/BA6U, BA7/BA7U)
For some stroke patterns, there is another attachment screw on the side cover between two
screws on right and left ends.
Make sure to remove them all.
2) Use a spatula to push the grease in between the slider and the base, or supply grease with a
grease injector and move the slider to spread the grease out evenly.
• Confirm the ball feeding surface on the guide is glossy with oil of the grease. Do the same work
again and again till the grease gets spread out enough.
• In case excess grease has been applied, wipe it away.
(Note) For brake-equipped type, connect a controller and operate it with JOG operation.
Caution: Supplying too much grease may increase sliding resistance and load to the motor,
resulting in a drop of performance.
