404/406XR Series Engineering Reference
The following performance information is provided as a supplement to the product specifications pages. The following graphs
and formulas are used to establish the table life relative to the applied loads. 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 life/load, it is
critical to include the weight of all positioning elements that contribute to the load supported by the primary axis.
Table Life/Load Chart
Compression (normal load)
This graph provides a “rough cut”
evaluation of the support bearing
life/load characteristics. The curves
show the life/load relationship when the
applied load is centered on the carriage,
normal (perpendicular) to the carriage
mounting surface. For final evaluation
of life vs. load, including off center,
tension, and side loads refer to the
charts and formulas found on our web
site www.parkermotion.com.

Thrust (axial load)
This graph illustrates table ballscrew life
relative to the axial load.
