HYBUFF – G-series

HYBUFF is our more standardised buffer products developed in order to be able to supply you with cost efficient solutions to your energy absorption needs.


We can offer a wide range of buffers from our HYBUFF
G-series, where the G stand for Gas hydraulic buffers.

The HYBUFF G-series is developed for applications where an energy stop device is needed. The robust design gives good stiffness suitable for higher forces. It has a cylinder with oil and hollow piston rod containing the reservoir.


The hollow rod contains a floating piston, separating oil and gas. The damping force is achieved by a flow restriction regulated by the metering pin. The metering pin at the centre of the buffer regulates the flow area to be more restricted when the buffer is being compressed.
