Keyway

Piston rod end deviating from standard

With a block cylinder, a side keyway can optionally be created in the housing. This keyway serves to absorb forces, and at the same time can be used for precise positioning. With higher forces the hydraulic cylinder  must provided with an additional rearwards support. 3 Bilder (siehe unten)

Caution: The bases of calculation for machine elements must also always be taken into account for the mounting of hydraulic cylinders. The tightening torques must be adapted appropriately depending on whether the screw connections are loaded axially or radially, for example. Thus when calculating the mounting it is necessary to consider not only the static forces, but also the possible high dynamic loads of hydraulic cylinders.
