MPS75SV Hardware Manual Maintenance
Lubrication
Take the opportunity during the lubrication procedure to inspect the precision rail guides for any damage or
signs of wear.
For standard applications, use NSK LG2 grease on the precision rail guides and ball screw. For vacuum
applications, refer to the vacuum guidelines in
Section 1.3. for the appropriate grease. Only use the specified
grease as other greases may be incompatible.
If the application process uses only a small portion of travel for most of the duty cycle, periodically drive the
stage through full travel to redistribute the lubrication in the bearings.
For high-speed applications (i.e., near maximum speed at a duty cycle of 50%), frequent maintenance with
standard lubricants is required.
N O T E : Removing the upper axis on an XY, XZ, or YZ system will alter a precision alignment. Do not
remove the upper axis for lubrication and cleaning if possible.
1. Drive the carriage to one end of travel, and remove power from the stage.
2. Blow off the interior of the stage with clean, dry compressed air or nitrogen.
3. Remove all dirty or dried lubricant from the drive screw and the precision rail guides. Use a small
application of isopropyl alcohol with a clean, lint-free cloth or cotton swab.
4. Using a grease syringe, apply an approximate 2 mm diameter bead of lubricant to the drive screw
threads and precision rail guides.
5. Manually move the carriage to the opposite end of travel. Then repeat Steps 2 through 4 for the opposite
sides of the bearing rails.
6. Manually move the carriage through full travel three or more times to distribute the lubricant.
7. Repeat the grease application process three more times to reach the total replacement grease quantity.
8. Restore power to the stage.
