Installing a load
Install the load using hexagonal socket head screws (not
supplied) through the tapped holes provided on the end face
of the rack. When installing the load, always secure the rack
with a wrench so that the rack will not receive rotational force
while the load is affixed.

When installing the load, align the axial centerline of the rack with that of the load.
Maximum overhung load
Keep the overhung load received by the rack end to or below the permissible value, as applicable, specified in the
table below.

* The above values are valid up to an operating speed of 90 mm/s. If the motor is operated at any higher speed, do
not apply overhang load. If an overhang load is to be applied, provide an external guide, etc.
•
Be sure to keep the overhang load to the permissible limit or below. An excessive overhang load
may cause the rack bushes to wear quickly or sustain damage.
•
Even if the overhung load does not exceed the permissible value, it is recommended to still install
a guide, etc., to reduce or disperse the overhung load.
Maximum rotational torque (moment)
Keep the rotational torque received by the rack to or below the permissible value, as applicable, specified in the table.
Lineard motor model
Permissible rotational torque
(moment) on rack
LAS2B(F)
0.3 N·m (2.6 lb-in) or less
LAS4B(F)
0.5 N·m (4.4 lb-in) or less
Be sure to keep the rotational torque to the permissible limit or below. If the rack receives excessive
rotational torque, the rack bushing will wear quickly.
