What is the difference between safe maximum travel and safe maximum travel considering solid height?
Safe maximum travel considering solid height, is the travel you may achieve out of your coiled compression spring due to its limitations of the actual design. In case that the spring is able to safely travel down to its solid height, the amount of travel of the stated spring will be that of the solid height being subtracted from the coiled compression spring’s free length. Safe maximum travel, on the other hand, is the amount of travel that you may achieve out of your coiled compression spring if you were to increase its free length. As explained before, too much pitch between your coiled compression springs can cause your spring to not be able to compress down to it’s solid height or coil bind height, but if there is minimal pitch, you may be able to increase your coiled compression spring’s free length to obtain more travel.
