Lubrication
For the 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. 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 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. Using a grease syringe, apply an approximate 2 mm diameter bead of lubricant to the relief area below
the bearing surfaces as close to the cage as possible equal to roughly ¼ of the overall length of the
bearing rail. Repeat this for both rails.
5. Manually move the stage to the opposite end of travel. This will work the grease into the 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. Gently move the stage table back and forth through travel by hand several times to distribute the
lubrication.
8. Repeat this procedure four times to fully grease the bearing surfaces.
