The following performance information is provided as a supplement to the product specifications pages. The
useful life of a linear table at full catalog specifications is dependent on the forces acting upon it. These forc-
es include both static components resulting from payload weight, and dynamic components due to accelera-
tion and deceleration of the load. In multi
-
axis applications, the primary positioner at the bottom of the stack
usually establishes the load limits for the combined axes. When evaluating life versus load, it is critical to
include the weight of all positioning elements that contribute to the load supported by the primary axis. The
following graphs and formulas are used to establish the table life relative to the applied loads.

This chart provides an evaluation of the linear
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 versus load, including
off center, tension, and side loads, refer to the
pitch moment chart for the short carriage units or
the bearing load charts (next page) for the long
carriage units.
This chart illustrates table ballscrew life relative
to axial (thrust) load.
This chart illustrates table linear bearing life rela-
tive to pitch moment for the short carriage units.
