Selection and installation
Check stroke, energy per cycle and hourly energy together with impact speed, cycle rate, driving force and available installation space. Use external adjustment to match the application; confirm the contact accessory and mounting thread for this model.
Series working principle
The piston forces oil through metering passages to dissipate impact energy. Turning the adjustment knob changes the effective flow area; the return mechanism resets the piston after the load is removed.
Catalog application and mounting notes
EKL42X25 is an industrial shock absorber with a 25 mm stroke and an M42 × 1.5 mounting thread. The approved product record specifies an operating velocity range of 0.08–1.30 m/s. The EKD catalog provides the model dimensions alongside the EK42 and EK64 family. Check both energy per cycle and hourly energy against the actual moving mass, drive force and cycle rate. Confirm the mounting dimensions, usable travel, stop position and return clearance for the machine before ordering; do not substitute standard EK velocity ratings for this EKL model.
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.
