SSC Spring Engineering vs SpringCalc

Convert springs, engineer new springs, compare drum specifications, calculate springs by IPPT, design springs for rolling steel doors, calculate approximate pull, or determine the maximum lift a spring/drum can lift on any job at any time. Application developed by Service Spring Corporation - a leader in spring manufacturing and customer service in the overhead door industry.

SpringCalc is a professional engineering calculator for mechanical springs. Enter any subset of spring parameters and SpringCalc solves for the rest — wire diameter, mean diameter, coil count, free length, spring rate, force, stress, safety factor and predicted fatigue life. Features: • Three spring types: Compression, Extension, Torsion • 15 built-in materials (Music Wire, Hard Drawn, Oil Tempered, Chrome Silicon, Chrome Vanadium, 302/304/316/17-7 PH Stainless, Phosphor Bronze, Beryllium Copper, Monel 400, Inconel 600/X-750/718) with JIS aliases (SWP-A/B, SUS302/304/316-WPB, SWOSC-V, etc.) • ASTM/SAE and JIS B 2704 calculation standards • Constraint-based solver with Wahl factor stress correction • Goodman + Basquin fatigue life prediction with environmental and temperature derating • Force-deflection and S-N curves via Swift Charts • 3-candidate design suggestion when system is under-determined • Standard wire gauge snap (ISO 2702 / SWG) • Custom material editor • Metric, Imperial and Mixed (mm/kgf) units • PDF and text report export • Save designs locally with SwiftData • Localized in English, Traditional Chinese and Japanese References: Shigley's Mechanical Engineering Design 10e Ch.10, JIS B 2704:2009, JIS B 2705:2014, SMI Handbook of Spring Design. All calculations run entirely on-device — no account, no cloud, no tracking.
