These charts are to be used to evaluate long car-
riage units. They should be used in conjunction
with the corresponding formulas on the following
pages (also available at www.parkermotion.com)
to establish the life relative to load for each bear-
ing (four per table).
Several dimensions, which are specific to each
linear positioning table model, and the load ge-
ometry are required for these computations.
These dimensions are supplied in the catalog
information for each positioner. The dimensions
are referenced as follows:

nal spacing
