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

EN36x25 is a fixed-type hydraulic shock absorber. The EKD catalogue lists a 25.0 mm stroke, 160.0 Nm maximum energy per cycle and 91,000 Nm maximum energy per hour for this model. Its standard body thread is M36 x 1.5. Confirm the damping code, impact velocity, available stopping travel, mounting envelope and actual cycle duty. The capped B version has a different overall length; verify the complete model code before ordering.

Replacement candidates for referenced models

Model-number relationships are recommendations only. Final selection must be based on the actual operating conditions, mounting and application review.
