Description:

?

Self-aligning?ball?bearings?are?constructed?with?the?inner?ring?and?ball?assembly?contained?within?an?outer?

ring?that?has?a?spherical?raceway.?This?construction?allows?the?bearing?to?tolerate?a?small?angular?

misalignment?resulting?from?deflection?or?improper?mounting.?Self-aligning?ball?bearing?is?consequently?

self-aligning?and?insensitive?to?angular?misalignments?of?the?shaft?relative?to?the?housing.

?

This?kind?of?ball?bearings?are?particularly?suitable?for?applications?where?considerable?shaft?deflections?or?

misalignment?are?to?be?expected.?Additionally,?the?self-aligning?ball?bearing?has?the?lowest?friction?of?all?

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?
