Okubizwa ngokuba yi-precision bearings kubhekiselele kuhlelo ngokwe-ISO Classification: P0, P6, P5, P4, P2.Amabakala anyuswa ngokulandelelanayo, apho u-P0 ikukuchaneka okuqhelekileyo, aze amanye amabakala abe ngamabakala achanekileyo.Iibheringi eziqhelekileyo ziibheringi zethu ezisetyenziswa ngokuqhelekileyo.Uthini umahluko phakathi kweebheringi ezichanekileyo kunye neebheringi eziqhelekileyo?Ngokokuqonda okuneenkcukacha, siya kwazisa umahluko phakathi kweebheringi ezichanekileyo kunye neebheringi eziqhelekileyo.

Uthini umahluko phakathi kweebheringi ezichanekileyo kunye neebheringi eziqhelekileyo?

Ukuchaneka kokuchaneka kwahlukile kwimveliso eqhelekileyo.1. Iimfuno zedimensional zahlukile.Ukuphambuka kwe-dimensional (i-diameter yangaphakathi, i-diameter yangaphandle, i-ellipse, njl.) yemveliso enebakala eliphezulu lokuchaneka lincinci kunexabiso elifunwa yimveliso enebakala elisezantsi lokuchaneka;

Ukuchaneka kokuchaneka kwahlukile kwimveliso eqhelekileyo.2. Ixabiso elifunekayo lokuchaneka kokujikeleza lihlukile.Imveliso echanekileyo ephezulu inokuchaneka okujikelezayo okuphezulu (i-radial runout yangaphakathi, i-radial runout yangaphandle, isiphelo se-radial runout, njl. njl.) kuneemveliso ezinomgangatho ochanekileyo osezantsi.Ixabiso elifunekayo lingqongqo;

Ukuchaneka kokuchaneka kwahlukile kwimveliso eqhelekileyo.3. Ubume bomphezulu kunye nomgangatho womgangatho wahlukile.Ubume bomphezulu kunye nomgangatho womphezulu wemveliso enomgangatho ophezulu wokuchaneka (uburhabaxa bomphezulu, ukutenxa kwisetyhula, ukutenxa kwegroove, njl.njl. wendlela yomdyarho okanye umjelo) Iimveliso ezingaphantsi komgangatho wokuchaneka zifuna amaxabiso angqongqo;

Iibheringi ezichanekileyo zahlukile kwiibheringi eziqhelekileyo.4. Iimveliso ezinamabakala aphezulu achanekileyo ziluncedo ngakumbi kunezo zamabanga achanekileyo.

Kwinkqubo yokusebenzisa ukuthwala, ukuchaneka ngokuchanekileyo okanye ukuthwala okuqhelekileyo kukhethwe ngokweemfuno ezithile zangempela, ukwenzela ukuba isixhobo somatshini okanye icandelo linokusetyenziswa ngcono.
