Formula

## Rolling Bearing L10 Life The L10 life is the number of revolutions (or hours) at which 90% of identical bearings will survive. ### Formula **L10 = (C/P)^p x 10^6 revolutions** **L10h = L10 / (60 N)** (hours) where C is the dynamic load rating from the manufacturer, P is the equivalent dynamic bearing load, N is speed in RPM, and p is the life exponent (3 for ball bearings, 10/3 for roller bearings).

Esempio Risolto

A ball bearing with C=50 kN, operating load P=10 kN, at 1500 RPM.

  1. 01C/P = 50/10 = 5
  2. 02L10 = 5^3 x 10^6 = 125 x 10^6 = 125,000,000 rev
  3. 03L10h = 125,000,000 / (60 x 1500) = 1,388.9 hours
  4. 04At 8 hours/day, this is about 174 operating days.
