4.2. Cleaning and Lubrication
Cleaning
Before using a cleaning solvent on any part of the AGR, blow away small particles and dust with nitrogen or,
less preferably, clean, dry, compressed air.
Any external metal surface of the AGR 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 worm gear drive mechanism, use Mobilith SHC 100 grease.
N O T E :
AGR stages were previously assembled using Klubersynth BEM 44-461 US grease. Kluber-
synth BEM 44-461 US is compatible with the new Mobilith SHC 100 grease; however, AGR stages that
were assembled with Klubersynth can continue to use Klubersynth for regular maintenance lubrication.
AGR rotary stages are designed for easy maintenance of the worm drive system. The drive mechanism can
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
. 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.
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.
