28 192-550003N10 ETH ATEX December 2019
The rod guide is smooth running and can easily slide out of the rod guide module
depending on its position. Hold the rod guide horizontally.
 Pull out the front plate with the guide rods from the rod guide module and set
them aside.
 Slide the rod guide module (see Figure 8 Pos. 1) onto the centering collar of the
ETH cylinder.
Please note: with the relubrication option in the centre of the profile, the
lubrication opening in the profile can be concealed by the guide rods.
 Screw together the rod guide module with the screws supplied (see Figure 8 Pos.
2) and the required tightening torque. For tightening torques see chapter 2.1.2.2
screw tightening torques for the mounting of the ETH cylinder on the customer’s
sde, option F.
 Loosen the screw (see Figure 8 Pos. 5) thus the lock nut (see Figure 8 Pos. 4)
can move freely.
 Slide the front panel with the guide rods back into the rod guide module.
 Turn the lock nut on the piston rod of the ETH cylinder and lock it with the
hexagon nut (see Figure 8 Pos. 6).
 Clamp the lock nut with the front panel by tightening the screw (see Figure 8 Pos.
5) with the required tightening torque. To avoid damaging the cylinder, the lock
nut must be used to hold the cylinder in place.Tightening torques: ETH032 = 6,5
Nm, ETH050 = 16 Nm, ETH080 = 29 Nm.
For power transmission from the rod guide module to your application please use
dowel pins.
We recommend to secure the screws with a liquid bolt retaining compound (e.g.
Loctite242)
2.1.3. Mounting of the payload
2.1.3.1 Side Load
Please observe that with ATEX certified ETH cylinders no lateral forces are being
applied to the cylinder rod.
Use suitable guiding units, e.g. the rod guiding option R (see in the catalog section
following the mounting instructions) or external guiding units.
2.1.3.2 Mounting of the payload
The piston rod of the ETH cylinder is equipped with an internal anti-rotation
device. When fixing the load on the thrust rod end, do always apply counter
pressure on the respective flat, (KV (SW), see ETH catalogue) with an
appropriate tool!Otherwise, the internal anti-rotation protection might be
damaged.
