Bergen Pipe Supports Snubbers & Restraints catalog

Hydraulic Snubbers At Bergen Pipe Supports we continually strive to meet the

Key features of the SNG range of snubbers are

needs of our customers and the latest development in our range of hydraulic snubbers brings about some significant benefits. With over 40 years' experience of manufacturing hydraulic snubbers contributing to the evolution of this new model we are able to offer a world-class product to our global market.

. .

I

The new hydraulic snubber is presented in a compact, symmetrical envelope with an integral, pressurised fluid reservoir that means they can be installed in any orientation.

The use of corrosion resistant materials means that snubber bodies no longer need to be painted and installation in harsh environments is less of a concern than before.

By integrating the fluid reservoir within the length of the main cylinder we have considerably reduced the overall length of the snubber and the redefined range of sizes means that this unit willfit within the same space as some of main competitors units. We offer nine .1000kN with sizes giving load capacities of up to strokes of up to 300mm.
