Selection and installation
Check operating stroke, energy per cycle and per hour, impact speed, driving force and mounting thread. The catalog distinguishes recommended operating stroke from piston-rod length (maximum travel); they are not interchangeable. Confirm service-life expectations and material options for the actual duty.
Series working principle
Hydraulic damping dissipates impact energy within a sealed assembly. The appropriate design depends on the duty cycle, environment and required stopping behaviour.
Catalog application and mounting notes
The catalog lists ES18983 as a general-purpose model for the mold-closing position, with a buffer cap and a 15-million-cycle service-life statement. Confirm the cap contact surface, mounting thread and published operating limits for the machine.
