With strokes greater than 16mm, our long stroke dampers are suitable for mechanisms that require the damping action to be spread over a long course. Long stroke dampers are usually needed for systems with heavier weights or faster initial speeds. They operate in temperatures from 0°C to 40 °C (from 32 °F to 104 °F).

mechanical (without spring: the piston rod is mechanically pulled out into the starting position) or automatic (with spring: the piston rod is automatically reset by the internal spring).

Customization Options-

For optimal damping performance, we can adapt our standard dampers by customizing their damper connection, damping force and damping characteristics.
