Bearing Life Calculator

L10 life from dynamic load capacity and equivalent load, per ISO 281.

The C value already reflects your bearing's specific material and manufacturing quality — always use the exact C from your bearing's own manufacturer datasheet, not a generic estimate.

Enter to also compute life in hours.
