Constant hangers and constant supports Witzenmann

Constant hangers and constant supports


HYDRA® constant hangers and constant supports are mobile pipe supports with constant load-bearing behaviour and are necessary if greater vertical movements (>60 mm) have to be absorbed. All rotatable bearings are a combination of polished, stainless steel axles and PTFE composite bearings that guarantee low friction levels. Optimum corrosion protection as well as problem-free assembly and connection to the support structure guarantee maintenance-free use.
