I-compression spring ngumthambo wokugcina okhokhelwa ngokwaxial
Isisekelo sesayizi esetshenziselwa kuyo kuyinto yezingubo, enjalo, enesithakazelo esiningi se-coil yestili. Izithambo zingaba ngokwanele zonke, kodwa izithambo zezikhuselo zingaba nezinye izithambo ezinhlobonhlobo njengoba zezingubo, zezingqondo, ezinyakazayo ezikhulu kanye nezincane, njengoba kanye nezinye izinhlobonhlobo ezifanayo. Kukhona isikhala esisodwa phakathi kwamathambo omthambo, futhi uma kutholakala kwezinto ezihambisanayo, umthambo uyothuthuka futhi uyothuthukisa, ukugcina isimo sokuthuthuka.
