These charts are to be used in
conjunction with the corresponding
formulas found under Product

to establish the life / load for each
bearing (4 per table).
Several dimensions, which are specific
to each linear positioning table model,
and the load geometry are required for
these computations. These dimensions
are supplied in the catalog information
for each positioner. The dimensions are
referenced as follows:
d1 – bearing block center-to-
center longitudinal spacing
d2 – bearing rail center-to-center
lateral spacing
da – rail center-to-carriage
