IF you have a catalogue showing technical details of the diaphragm springs you hold IN STOCK having outside diameters betwen 138mm and 165mm would you please e mail a copy to me. Technical data such as Outside and Inside diameter - number of release ears - spring thickness - pressure line diameter used for load values such as MAXIMUM and MINIMUM load and load at the spring flat point- the free height / springthickness ratio.The Italian manufacturer we have used in the past is no longer able to supply us with the diaphragm springs we require. Order size would be several hundred.
