Compression Spring

indicative

Design standard

Calculation standard

Sets screening knobs for Indicative practice — not product type or catalog geometry

Standard SF / service factors for compression, extension, or torsion springs. Spring type stays free.

Typical Auto-design directions for compression springs.

Option	Basis	Pass	Tradeoff
Compact spring	Small envelope	Check stress	Higher stress
Balanced spring	Target rate	Pass expected	Moderate envelope
Long-life spring	Lower stress	High fatigue margin	Larger size
