SPEC compression springs provide design engineers, draughtsmen,
production an maintenance departments with precision-engineered
springs in an economical and time-saving way.
Compression springs are available in 2 types: Compression Spring A
(European metric sizes) and Compression Spring A (American imperial
Music wire to DIN 17223, Klasse C. No.1, 1200. BS5216 ND3 of
HD3-AMS 5112.Stainless steel wire to DIN 17224. No. 1.4310 BS 2056

Load values shown are for music wire and are based on a service
life of 50.000 cycles at 0.50 stress range. For normal service
springs should not be compressed below L1.
Normal wire oiled. Shot-peened and plated finishes supplied on
request. Allow sufficient additional time for special finishes.To
determine the load at any working length use rate x proposed
deflection.1 lb = 4.448 Newtons1 Newton = 0.225 lb.
