2.1.3. Mounting Instructions
2.1.3.1 Side Load
Please respect the maximum permissible side loads depending on the vertical or
horizontal mounting position.

2.1.3.2 Mounting of the payload
When mounting the payload, please make sure that no torque is applied to the
thrust rod. Use the flat on the thrust rod to apply counter pressure, see indication
"SW" "Cylinder Rod Version": please refer to ETH catalogue.
Figure 9: Mounting of the payload
When fixing the load on the thrust rod end, do always apply counter pressure on
the respective flat, KV (SW) with an appropriate tool!
Otherwise, the internal anti-rotation protection might be damaged.
Connect the payload always with the end of the thrust rod so that occurring lateral
forces are minimized. If the payload is separately guided, even minimal deviations
between this guiding system and the cylinder length axis can generate high lateral
forces and reduce the service life of the electro cylinder considerably.
The possibilities to avoid this problem:
Use a flexible coupling at the thrust rod end.
This coupling can compensate up to 3 mm axial offset and up to 10° angular
offset.
Use other thrust rod connection elements (accessories), which are able to
compensate certain deviations such as rod clevis or spherical rod eye
Use a flexible cylinder fixing device (accessories) such as rear clevis or center
trunnion.
Do only use the rod ends supplied by Parker.
Only use the nut delivered with the rod end option M as counter screw.
The connection provided from the customer is always screwed in the thread of
"Cylinder Rod Version": please refer to ETH catalogue.
