style="text-indent:25px">角接觸球軸承用保持架：一般的角接觸球軸承使用的是酚醛膠布保持架,這種保持架的材料是較常規(guī)，也是較經(jīng)濟(jì)的，而且也可以滿足軸承的各方面性能，-般分為外引導(dǎo)和內(nèi)引導(dǎo)兩種。為了提高軸承的各方面性能, HBB公司也開(kāi)發(fā)了些其他材料的保持架,例如工程塑料和碳纖維的，適用這兩種材質(zhì)的保持架一般采用球引導(dǎo)。相比其他材質(zhì)的保持架，工程塑料保持架不*重量輕(比重*為1/6)，而且具有自動(dòng)潤(rùn)滑性能優(yōu)良、摩擦系數(shù)小的特點(diǎn)。因此，高速旋轉(zhuǎn)時(shí)軸承發(fā)熱少，具有優(yōu)越的高速特性。而且保持架磨損帶來(lái)的油脂的劣化少，普遍適用于機(jī)床主軸軸承等保持架。定位預(yù)緊：沿著施力方向加上預(yù)緊力，讓間隙為0。合肥71809ACTA角接觸球軸承</p><p
