DESIGN OPERATION AND MAINTENANCE CONSIDERATIONS

Lube oil will have a natural tendency to migrate along the shaft from the bearing to the barrier seal requiring the bearing cavity to be designed to minimize the exposure of the barrier seal to lube oil Flooded bearing drains place greater demands on barrier seals so it is also imperative to size and locate bearing cavity drain porting and
