Double Helical Spring

Double helical springs feature a coaxial inner-outer counter-wound structure to deliver graded load bearing, anti-deflection performance and broadband vibration isolation, serving as a high-end precision elastic solution for industrial scenarios requiring high precision, high stability and heavy loads.

Material:Common Materials 60Si2Mn: General-purpose spring steel with good toughness and cost performance, applied to automotive suspension and ordinary heavy machinery under normal loads. 50CrV4: Heavy-duty alloy spring steel with excellent fatigue and impact resistance, ideal for machine tool spindles, presses and other high-load applications. 17-7PH / 316 Stainless Steel: High temperature resistance, corrosion resistance and low outgassing, suitable for hydraulic sealing, spring-energized seals, semiconductor and aerospace industries. Beryllium Copper: High elasticity, low friction and high cleanliness, widely used in precision instruments, medical devices and miniature test fixtures.
