Mounting notes2.1.3.1 Side LoadPlease respect the maximum permissible side loads depending on the vertical orhorizontal mounting position.Permissible side load: See from page 13 in the catalog section (following themounting instructions).2.1.3.2 Mounting of the payloadWhen mounting the payload, please make sure that no torque is applied to thethrust rod. Solution: On the cylinder rod there are spanner flats for locking, seedimension “SW” (width across flat) “Thrust rod version”: see in the catalog section(following the mounting instructions).Connect the payload always with the end of the thrust rod so that occurring lateralforces are minimized. If the payload is separately guided, even minimal deviationsbetween this guiding system and the cylinder length axis can generate high lateralforces and reduce the service life of the electro cylinder considerably.There are two 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 angularoffset.◆ Use other thrust rod connection elements (accessories), which are able tocompensate certain deviations such as for example rod clevis or spherical rodeye◆ Use a flexible cylinder fixing device (accessories) such as for example rear clevisor center trunnion.Thrust rod version: see from page 23 in the catalog section (following the mountinginstructions).
