Equivalent Dynamic Load

indicative

Design standard

Calculation standard

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

Basic rating life L₁₀ and static safety s₀ per ISO 281 / ISO 76. Use any bearing family.

Validate — verify what you entered

Auto-design runs a solver-backed sizing search, applies the best candidate, then runs the full validation check.

Most engineers struggle with when P equals Fr versus X·Fr + Y·Fa. This tool shows the factors and the Fa/Fr vs e decision — not just the number.

Option	Basis	Pass	Tradeoff
Compact series	Smallest bore/C	Check life	Lower reserve
Standard series	ISO 281 life	Pass expected	Balanced
Heavy series	High C	High reserve	Larger envelope
