Bearing Life Calculator
Estimate basic bearing life using dynamic capacity and equivalent load.
Mechanical engineering safety note
Mechanical engineering calculators on ToolsBing are preliminary educational and planning tools only. Verify material properties, machine specifications, safety factors, operating conditions, standards, and design assumptions with qualified engineers, manufacturer data, and applicable codes before design, procurement, or operation.

Formula and assumptions
Basic life estimate uses (C/P)^3 adjusted by speed
This calculator uses simplified engineering assumptions. Real systems may require safety factors, manufacturer curves, fluid properties, thermal limits, fatigue checks, tolerances, and professional review.
