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 ED4.0x2 heavy-duty buffer has a published 50 mm stroke. The catalogue distinguishes straight-line impact ratings from applications with side load; confirm the actual impact direction and the selected mounting arrangement before ordering.
