Maintenance
4.2. Cleaning and Lubrication
D A N G E R : To minimize the possibility of bodily injury or death, disconnect all electrical
power prior to performing any maintenance or making adjustments to the equipment.
W A R N I N G : In applications that have multiple stages bolted together to form multi-axis
systems, the orthogonality may be lost if the stage tables of the support stages are loosened.
Precision aligned stages should not be loosened or disassembled.
W A R N I N G : Further disassembly of the stage is not recommended because proper
assembly and calibration can only be done at the factory. In addition, a laser interferometer is
required for post assembly verification to maintain warranties. Contact Aerotech for more
information.
Cleaning
Before using a cleaning solvent on any part of the ANT95L, blow away small particles and dust with nitrogen
or, less preferably, clean, dry, compressed air.
Any external metal surface of the ANT95L can be cleaned with isopropyl alcohol on a lint-free cloth.
W A R N I N G : Make sure that all solvent has completely evaporated before attempting to
move the stage.
Lubrication
For the linear roller bearings, use Kluberplex BEM 34-132 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. The motor is completely non-contact
and requires no lubrication.
N O T E : During the lubrication procedure, inspect the linear motion guides for any damage or signs of
wear.
Lubrication Procedure
1. Drive the stage table to one end of travel and remove power to the stage.
2. Remove any accumulated dust or debris that is visible inside of the assembly.
3. Remove any dirty or dried lubricant from the v-channels of the linear bearing rails. Use a clean, lint-free
cloth with a side-to-side motion. Use a swab soaked in isopropyl alcohol to remove stubborn debris.
4. Apply a thin, continuous film of lubricant to the exposed v-channels of the cross rollers on both ends of
the stage. A good quality, natural bristle artist's brush makes an excellent applicator. Do not use any
applicator that could scratch or otherwise damage the v-channels.
5. Manually move the stage to the opposite end of travel. This will work the grease into the linear bearing
guides. The stage table should move freely with little resistance.
6. Repeat steps 2 through 4 for any areas covered by the original table position.
7. Restore power to the stage; drive the stage table back to its original position to redistribute lubricants.
