Theoretical Output
Refer to the “Single acting, Spring return cylinder” in Theoretical Output
1 of Technical data 3 on page 1573. In the case of the spring extend
style, the force at OUT side will be the ending force of the spring return,
and that at the IN side will be the amount of the IN side force of the
double acting style cylinder from which the beginning force of the spring
return has been subtracted.
Caution
1. During installation, secure the rod cover and tighten by applying an
appropriate tightening force to the retaining nut or to the rod cover
body.
If the head cover is secured or the head cover is tightened, the
cover could rotate, leading to the deviation.
2. Tighten the retaining screws to an appropriate tightening torque
within the range given below.
ø6: 2.1 to 2.5 N·m, ø10: 5.9 to 6.4 N·m,
ø16: 10.8 to 11.8 N·m
3. In the case of a single acting cylinder, do not operate it in such a
way that a load would be applied during the retraction of the piston
rod of the spring return style, or during the extension of the piston
rod of the spring extend style. The spring that is built into the
cylinder provides only enough force to retract the piton rod. Thus, if
a load is applied, the piston rod will not be able to retract to the end
of the stroke.
4. In the case of a single acting cylinder, a breather hole is provided
in the cover surface. Make sure not to block this hole during
installation, as this could lead to a malfunction.
5. To remove and install the retaining ring for the knuckle pin or the
clevis pin, use an appropriate pair of pliers (tool for installing a type
C retaining ring).
In particular, use a pair of ultra-mini pliers for removing and
installing the retaining ring on the ø10 cylinder.
6. In the case of auto switch rail mounting style, do not remove the rail
that is mounted. Because retaining screws extend into the cylinder,
this could lead to an air leak.
