4.2. Cleaning and Lubrication
DANGER: Before you do maintenance to the equipment, disconnect the electrical power.
In general, if the stage operates in a clean environment, it should be cleaned and lubricated annually or
every 500 km (whichever comes first). For stages that are operated under conditions with excessive
debris, the stage should be cleaned every six months. For high-speed applications (those near max speed
at a duty cycle of 50%), more frequent maintenance with standard lubricants will be required.
When you clean and/or lubricate components of the PRO225SL/SLE series stage:
1. Be sure to use a clean, dry, soft, lint-free cloth for cleaning.
2. Before you use a cleaning solvent on any part of the stage, blow away small particles and dust with clean,
dry, compressed air.
3. Take the opportunity during the lubrication procedure to inspect the motion guides or bearings for any dam-
age or signs of wear.
4. 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.
5. We recommend that you do not disassemble the stage beyond the instructions given in this manual. Proper
assembly and calibration can only be done at the factory. Contact Aerotech for more information.
For stages equipped with foldback motors, you should check the belt tension when you clean or
lubricate the stage. Refer to
Cleaning
Use isopropyl alcohol if you must use a solvent to clean the stage. Harsher solvents, such as acetone,
could damage the plastic and rubber seals on the ball screw and bearing trucks.
WARNING: Make sure that all solvent has completely evaporated before you move the
stage.
Lubrication
You should only use Kluberplex BEM 34-132 as the standard lubricant for PRO225SL/SLE second
generation stages. Second generation stages can be distinguished from first generation stages by the
curved hardcover on the second generation stage.
IMPORTANT: First Generation stages were manufactured with THK AFE-CA grease as the
standard lubricant. THK AFE-CA grease is not chemically compatible with Kluberplex BEM
34-132 and the two should not be used interchangeably. First generation stages in the
field should continue to use THK AFE-CA grease for regular maintenance lubrication.
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.
