Selection and installation
Automated warehouses, rail systems, gantry cranes and heavy production lines. Review hourly energy and the required return cycle.
Series working principle
Metered hydraulic flow absorbs energy, while the accumulator accommodates displaced oil. Orifice configuration and accumulator options depend on the application and cycle rate.
Catalog application and mounting notes
The ED1.5x2 heavy-duty buffer has a published 50 mm stroke. The catalogue ratings assume an ideal straight-line impact; confirm the actual impact direction, any side load and the selected mounting arrangement 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.
- Published optimal impact velocity range
- 0.05-7.62 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
- Nominal return force with BA: 220 NNominal return force without BA: 320 N
- Operating temperature
- Series catalog temperature, optional fluid and seals: -35 … 100 °CSeries catalog temperature, standard configuration: -10 … 60 °C
- Allowable side load or angle
- Not established in the published model data — engineering confirmation required
- Maximum impact force
- 70060 N
- Maximum thrust force
- 70060 N
Temperature ranges are series catalog references. Confirm the fluid, seals and ordered configuration; an optional range is not a standard-model rating.
Return force is separate from allowable impact force and drive thrust. BA denotes the optional bladder accumulator; do not assume it is fitted.
Catalog operating conditions
- Catalog cycle limits: 60 cycles/hour with BA, 30 without BA. Also check energy per cycle, hourly energy, temperature and full return before the next impact.
- For impact speeds above 4.5 m/s or any side loading, request engineering review. The energy tables assume linear impact.
- For strokes of 300 mm or more, the catalog advises against rear-flange-only mounting; review front-and-rear flange or foot mounting.
- Below 5% of the maximum rated energy per cycle, the catalog calls for a smaller model. Confirm low-energy damping for the actual application.
