Extension Spring, Medium Heavy / Heavy Load
A spring stores and releases force over a set travel. Wire diameter, outside diameter and free length together give the rate; the allowable deflection class tells you how far it can be compressed before it takes a permanent set. Stainless grades are used where humidity or washdown is a factor.
