401-402XR Series Technical Data
The useful life of a linear table at full catalog specifications is dependent on the forces acting upon it. These forces include
both static components resulting from payload weight, and dynamic components due to acceleration/deceleration of the load.
In multi-axes applications, the primary positioner at the bottom of the stack usually establishes the load limits for the
combined axes. When determining load/life, it is critical to include the weight of all positioning elements that contribute to the
load supported by the primary axis. The life/load charts are used to establish the table life relative to the applied loads.

Table Load Chart
The “Table Load”
chart
is intended to
provide a rough-cut
evaluation “life/load”
characteristics of the
carriage support
bearings. This curve
is based on the
applied load being
centered on the
carriage, normal to
the carriage
mounting surface.
Thrust Load Chart
The “Thrust Load”
chart
illustrates table
ballscrew life relative
to the axial load.
