2-3. Mounting and Installation
1) There is a tolerance location diameter at the base of the cover
mounting threads specifically for accurate alignment when
mounting.
Caution
1) Do not apply excessive lateral load to the piston rod.
The bold solid lines in Fig. 1 show the allowable lateral load on the cylinder for a certain
stroke length.
Refer to 2-6. Allowable kinetic energy. (Page 11)
Fig. 1 Allowable lateral load applied to rod end
Calculation for excessive lateral load:
Minimum operating pressure value after the device is mounted (MPa) = Cylinder's
minimum operating pressure(MPa) + {Load weight(kg) × Guide friction coefficient /
Cylinder's cross section (mm2)}
If the product is found to operate smoothly with the calculated pressure, it can be judged
that the alignment of the guides have not created additional loading on the cylinder.
2) Make sure to connect the piston rod and the load so that their axial
centers and movement directions match.
If they do not match, stress could be applied to the rod and the cylinder tube, causing the
inner surface of the cylinder tube, the bushing, the rod surface, and the seals to wear
and become damaged.
