Hi all,
I'm looking at some plant roughly 27 years old and have an NHK spring hanger. I cannot for the life of me find any information on NHK springs, let alone the catalogue PH-82C as it is referenced on the drawings. To the moderators - are you able to please advise the spring rates for a VS30 size 12 NHK spring please? Is there anyway to view the NHK.HGR data file in the installation directory?
Cheers

It appears that the NHK VS30 Size 12 spring has a spring rate of 118 N/mm and a recommended load range of 5678N to 8325N.
(I ran a small model that selected that spring.)

Thanks Dave
