412LXR 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.
Bearing Load Chart
The “Bearing Load” chart
is to be used in conjunction
with the corresponding
formulas on the following
pages to establish the life/load
for each bearing (4 per table).
Several dimensions and the
load geometry are required
for these computations. The
dimensions are referenced
below.
