Appendix C Stacking Stages
Specifications for Stacked
Stages Linear stage specifications are based on mounting the stage to a precision base
along the entire length of the stage, and MPAS stage specifications follow this
convention. In the case of stacked stages, the top axis is no longer supported along
its entire length, and this alters both the precision and the load carrying capability
of that stage. Furthermore, linear stage specifications are based on a specified test
payload with a low center of gravity that is centered on the carriage. Deviations
from the test payload condition can impact the performance of both the top and
bottom linear stages.
The following table provides information about the payload that the top stage, or
axis, can carry without derating the life of its bearings from those specified for the
same stage mounted as a single-axis stage on a precision base.
