Selection and installation
Automation mechanisms and precision motion stops. Match impact speed, effective mass and energy to the selected model.
Series working principle
As the piston travels, it progressively closes metering holes and changes the oil-flow area. A return spring resets the absorber for the next impact.
Catalog application and mounting notes
EN20x22 is a fixed-type hydraulic shock absorber with a catalog stroke of 22.0 mm and a maximum energy rating of 62.0 Nm per cycle. The standard model has an M20 x 1.5 body thread and a catalog overall length of 118.4 mm; the capped B version uses the 130.3 mm A1 dimension. Confirm the damping code, impact speed, available stopping travel and hourly duty for the actual machine, and verify the complete model code before ordering.
Engineering limits to confirm for this model
Published data below describes the model. A missing value needs confirmation; it is never a passed check. Use the cited model drawing and operating conditions when requesting a review.
