Auton py\u00f6r\u00e4n laakerit aiemmin on eniten paria yksirivisi\u00e4 kartiorullalaakereita tai kuulalaakereita. Teknologian kehittyess\u00e4 auton napayksik\u00f6it\u00e4 on k\u00e4ytetty laajalti autoissa. Navan laakeriyksik\u00f6iden k\u00e4ytt\u00f6 ja k\u00e4yt\u00f6n lis\u00e4\u00e4minen on kehittynyt kolmanteen sukupolveen: ensimm\u00e4inen sukupolvi koostuu kaksirivisist\u00e4 kulmalaakereista. Toisessa sukupolvessa laakerin kiinnitt\u00e4mist\u00e4 varten on ulommalla juoksuradalla laippa, joka voidaan yksinkertaisesti kiinnitt\u00e4\u00e4 akseliin mutterilla. Tekee auton huollosta helppoa. Kolmannen sukupolven navan laakeriyksik\u00f6ss\u00e4 k\u00e4ytet\u00e4\u00e4n laakeriyksikk\u00f6\u00e4 ja lukkiutumatonta jarruj\u00e4rjestelm\u00e4\u00e4. Napayksikk\u00f6 on suunniteltu sisemm\u00e4ll\u00e4 laipalla ja ulommalla laipalla, sisempi laippa kiinnitet\u00e4\u00e4n pultilla vetoakseliin, ja ulompi laippa kiinnitt\u00e4\u00e4 koko laakerin yhteen.
