Applications:?

?

?In?general,?ball?bearings?are?used?in?most?applications?that?involve?moving?parts.?Some?of?these?

applications?have?specific?features?and?requirements:

?

·?Hard?drive?bearings?used?to?be?highly?spherical,?and?were?said?to?be?the?best?spherical?manufactured?

shapes,?but?this?is?no?longer?true,?and?more?and?more?are?being?replaced?with?fluid?bearings.

?

·?German?ball?bearing?factories?were?often?a?target?of?allied?aerial?bombings?during?World?War?II;?such?

was?the?importance?of?the?ball?bearing?to?the?German?war?industry.[4]

?

·?In?horology,?the?company?Jean?Lassale?designed?a?watch?movement?that?used?ball?bearings?to?reduce?

the?thickness?of?the?movement.?Using?0.20?mm?balls,?the?Calibre?1200?was?only?1.2?mm?thick,?which?still

?is?the?thinnest?mechanical?watch?movement.[5]

?

·?Aerospace?bearings?are?used?in?many?applications?on?commercial,?private?and?military?aircraft?including?

pulleys,?gearboxes?and?jet?engine?shafts.?Materials?include?M50?tool?steel?(AMS6491),?Carbon?chrome?
