- The legacy page this was ported from shares its exact page title with four other spring calculators (disc/Belleville washer; torsion bar, solid; cantilever leaf spring; tension bar/rod spring) that are, despite the shared title, genuinely different spring types.
- Disc (Belleville washer) spring (shares this calculator's legacy page title, but a distinct spring type)
