Cylinders with end cover mountings
The end cover mountings are suitable for the installation
of all cylinders. However, cylinders with ball rail guide
must also be installed with foot mountings. End cover
mountings are supplied in pairs with screws.
Please note: The cylinder views vary according to
series (RTC or CKP).
Fitting the end cover mountings
Fitting the end cover mountings, RTC series
1. Place the cylinder on a firm, flat surface.
2. Fit a mounting at either end of the cylinder using the
screws supplied.
3. Attach each end cover to the mounting surface with
suitable screws or bolts.
4. Tighten the screws gradually to avoid tensions (see
table 1 for tightening torque).

Cylinders with foot mountings
Foot mountings are designed to also take axial loads.
When a complete cylinder with foot mounting is ordered
the requisite number of foot mountings is supplied
automatically. See the online product catalog for different
types of foot mountings and calculations of the required
number.
Foot mountings must always be used when
installing cylinders with ball rail guide, since the
load on these is normally high.
Foot mountings must always be mounted with the
specified torque (see table 2).

Positioning the foot mountings, RTC series (cylinder seen from
above)
For RTC cylinders, foot mountings with two screws are
typically used. Mountings with a single screw can be used
when required, for example when mounting on a frame.
They must be mounted with one pair at each end and
evenly distributed about one meter apart, with normal
loads on a solid surface.
With suspended mounting and heavy loads, where there is
a risk of bending the cylinder, the foot mountings may
have to be positioned more closely together (see online
product catalog).
Foot mountings must always be attached when
installing RTC-CG and RTC-HD. Always use all the
foot mountings supplied and distribute them as
evenly as possible.

Positioning the foot mountings, CKP series
For CKP cylinders, foot mountings with one screw (type 1),
two screws (type 2), or four screws (type 3) are used,
depending on what is suitable.
The foot mountings must be distributed evenly along the
length of the cylinder with a minimum number per meter
according to illustration. This is applicable to normal loads
on a solid surface.
