LX80L 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 com-
ponents due to acceleration/deceleration of the load. In multi-axes applications, the primary posi-
tioner 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.
Linear Bearing Life-Load All Travels
Moment Load – Life Curves
The effect of moment loading on the bearing life is dependent upon load and lever arm. The lever
arm in this case is measured from the center of the surface of the table to the point where the load
is applied. For dynamic loading, use the distance from the center of the table to the center of mass
of the load. The Life-Load charts show curves for various lever arm lengths (units in [mm]). Note
Pitch moments and Yaw moments use the same curves.

The precision linear bearings used in the LX80L are sized to provide virtually unlimited life,
100,000,000 inches of travel guaranteed. The bearings provide stable and accurate linear motion
while maintaining high rigidity even under combined of fluctuating loads. The double rail design
offers the best load capacity, straightness, flatness, and stability.
