Blower Bearing Life

Basics of Bearing Life: L10= (C/P)10/3 x a x106/60 ——- n L10 estimated bearing life in hours; estimated as the 90% reliability hours C = radial rating of the bearing P = radial load on the bearing a = life adjustment factor; ex: oil viscosity, oil quality, etc. n = rotational speed in rev/min Doubling load reduces life to one tenth Doubling speed reduces life by one half Drive Alignment and Belt Tension: From this we can see that bearing…
