Maintenance AGR Series Stage Hardware Manual
4.2. Cleaning and Lubrication
If a solvent is necessary for cleaning the stage, isopropyl alcohol should be used.
For the worm gear drive mechanism, Klubersynth BEM-44-461-US grease is the only approved lubricant for
standard stages.
4.2.1. Recommended Cleaning Solvents
Before using a cleaning solvent on any part of the stage, it is recommended that compressed nitrogen or
clean, dry air be used to blow away small particles and dust. Any metal surface of the stage may be cleaned
with isopropyl alcohol on a lint-free cloth.
4.2.2. Lubrication Procedure
The AGR series of rotary stages is designed for easy maintenance of the worm drive system. The drive
mechanism may be lubricated while the stage is under power and integrated in upper level systems providing
access to the lubrication ports are maintained. Access to the lubrication ports are provided by removing the
port cover screws shown in Figure 1-2. Prior to removing the screw, make sure the surrounding surface is
clean.
While the stage rotates (<5 rpm), slowly inject approximately 6 cc's of lubricant into the ports. Wipe clean
any excess lubricant and reinstall the port cover screws.
Figure 4-1 shows the effect of the addition of lubricant to the current draw of a typical AGR stage. With the
added lubricant the resulting current pull is much smoother, leading to much better mechanical performance
and maximum life of the product.
