１．Installation to Application
The rodless cylinder presented in this manual is not equipped with non-rotation device and allows
external slider to rotate. Also, the rod less cylinder can't resist direct large load and needs another axis
(LM guide etc.) as a guide to support the load.
1-1) Installation of cylinder body
Before installation of cylinder body, be sure to fix head covers at its both ends. (In other words, use
the cylinder with support at the both ends.)
Also, do not use the cylinder with fixed at external slider to avoid excessive moment applied to
bearing of the cylinder.
And, if the cylinder is mounted with axial compressing force applied, the cylinder tube is deflected and
operating failure may be caused. (Fig. 1)
Wrong example
Head
Foot
cover
Cylinder tube
Support at one end
Stud bolt
Cylinder tube
If the cylinder body is mounted by stud bolt etc.
with axial compressing force applied, the cylinder
tube is deflected and breaks alignment, operating
failure may be caused.
External
slider
Adjusting screw
(for play)
Eliminate the axial compressing force from the
cylinder body by adequate tool, such as shaft
with step. The play created between mounting
bracket and cylinder body can be adjusted by
adjusting screw etc.
