Maintenance of the positioning unit
The spindle and ball screw drive are lubricated with OWIS SST.F11 at the fac-
tory. SST.F11 grease in the 5 ml applicator can be obtained from OWIS under
OWIS order number 90.999.0011.
The ball bearing guideways are lubricated with OWIS SST.F2 at the factory.
SST.F2 grease in the 5 ml applicator can be obtained from OWIS under OWIS
order number 90.999.0002.
Obtain the SST.F11 and SST.F2 greases from OWIS; they cannot be purchased
from ZEISS.
Relubricating the positioning unit
Relubricate the positioning unit after approx. every 500 hours of use and at
least every 3 months.
Procedure
• Use a dry, lint-free cloth to remove used or contaminated grease and any
contamination from the guideways and from the threads of the spindle
and ball screw drive. Cleaning agents such as benzine or petroleum ether
are generally not required.
• Evenly apply a thin layer of SST.F11 to the entire thread surface.
Each of the four recirculating ball slides has a bore in which you can introduce
the SST.F2 grease using the grease applicator.
NOTE If the specified maintenance intervals are not observed, the motion of the po-
sitioning unit may become stiff and setting will become more difficult.
• Make sure that the positioning unit is lubricated at the specified intervals
Lubricants mainly consist of base oil and thickener. Some base oils and thick-
eners are not compatible with each other, and do not provide a homoge-
neous mixture. In such cases, there may be a tendency of hardening or pro-
nounced softening with the resulting risk of dripping. Therefore, avoid
mixing different lubricants and use the original lubricant only.
