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 ES18983F-BN as a general-purpose mold-closing model with a special impact head and a 15-million-cycle service-life statement. Its published M14 × 1.0 mounting thread and 82.7 mm total length are model-specific; confirm both before ordering.
