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.
Adjustable hydraulic construction
Catalogue cutaway showing the piston, metering path, return spring and external adjustment assembly. The arrows identify component positions rather than measured flow data.

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.
- Published optimal impact velocity range
- 0.3-3.5 m/s
- Effective mass range
- Not established in the published model data — engineering confirmation required
- Return time
- Not established in the published model data — engineering confirmation required
- Return force
- Not established in the published model data — engineering confirmation required
- Operating temperature
- Series catalog temperature, optional fluid and seals: -40 … 100 °CSeries catalog temperature, standard configuration: -10 … 80 °C
- Allowable side load or angle
- Not established in the published model data — engineering confirmation required
- Maximum impact force
- 20000 N
- Maximum thrust force
- 2890 N
Temperature ranges are series catalog references. Confirm the fluid, seals and ordered configuration; an optional range is not a standard-model rating.
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.
