No passado, os rolamentos das rodas dos autom\u00f3veis eram os pares de rolamentos de esferas ou de rolos c\u00f3nicos de uma fila. Com o desenvolvimento da tecnologia, as unidades de cubo de carro t\u00eam sido amplamente utilizadas em carros. A utiliza\u00e7\u00e3o de unidades de rolamento de cubo e a utiliza\u00e7\u00e3o de cada vez mais, desenvolveu-se para a terceira gera\u00e7\u00e3o: a primeira gera\u00e7\u00e3o \u00e9 composta por rolamentos de contacto angular de duas filas. A segunda gera\u00e7\u00e3o tem uma flange na pista exterior para fixar o rolamento, que pode ser simplesmente fixado no eixo com uma porca. Facilita a manuten\u00e7\u00e3o do autom\u00f3vel. A unidade de rolamento do cubo de terceira gera\u00e7\u00e3o utiliza uma unidade de rolamento e um sistema de travagem anti-bloqueio. A unidade de cubo \u00e9 concebida com uma flange interior e uma flange exterior, a flange interior \u00e9 aparafusada ao eixo de transmiss\u00e3o e a flange exterior monta todo o rolamento em conjunto. Os produtos da empresa s\u00e3o rodas de a\u00e7o sem c\u00e2mara de ar para cami\u00f5es ligeiros, rodas para cami\u00f5es pesados, rodas agr\u00edcolas e florestais sem c\u00e2mara de ar, rodas forjadas em liga de alum\u00ednio e magn\u00e9sio para autom\u00f3veis de passageiros. A empresa produz 4 milh\u00f5es de conjuntos de rodas por ano e os seus produtos s\u00e3o vendidos em todo o mundo. As exporta\u00e7\u00f5es representam a propor\u00e7\u00e3o de 50% e as vendas no mercado interno representam a propor\u00e7\u00e3o de 50%. \u00c9 um fornecedor estrat\u00e9gico da FAW, Sinotruk, Foton e outros OEM.
