All U.S. Motors-brand pool motors feature three layers of protection:
double-sealed ball bearings, lip seal and water slinger. The new
Aqua-Shield 56 Frame pool motor from Nidec Motor Corp. adds a fourth
layer: an internal bearing cover to provide moisture protection inside
the motor, where water and debris can damage windings and cause
premature failure.
