Extension Springs

Tension Helical Springs

Tension helical springs , also known as extension springs , are coiled springs designed to absorb and store energy by resisting pulling (tensile) forces. These springs elongate under load and return to their original length when the load is released, providing a restoring force that keeps components securely connected. Key Features: Design: Helical coils with hooks, loops, or other end attachments for easy installation and load transfer. Material: Typically made from high-strength carbon steel, stainless steel, or alloy steel for durability and fatigue resistance. Function: Provides a pulling force by extending under tension and returning to original shape when unloaded. Performance: Delivers consistent tension force, excellent fatigue life, and resistance to deformation. Sizes: Available in various wire diameters, coil diameters, lengths, and load ratings.
