EN Series
EN Non-Adjustable Hydraulic Shock Absorbers
Self-compensating non-adjustable shock absorbers for repeatable machine stops and high-frequency equipment.
Selector eligible absorber series
Working principle
Multiple orifices are progressively closed by piston movement, adapting the available flow area to impact conditions.
Construction
Integrated non-detachable structure with piston rod, coil spring, foam accumulator, check ring and multiple-orifice shock tube.
Applications
High-frequency precision equipment, automation stops, food processing and conveyor systems.
