What does Q, F, D mean - ANS -Quench, flush, drain
Balanced seal refers to? - ANS -Balanced by fluid pressure
Surface on which the balls or rollers of an anti-friction (rolling) bearing rotate is -
ANS -Race (raceway)
In a typical centrifugal pump, the outer ring (race) of an anti-friction (rolling
element) bearing has a __________ to the pump bearing housing bore - ANS -
