這種軸承具有接觸角,所以適于承受一個(gè)方向的軸向負(fù)荷,或合成負(fù)荷。結(jié)構(gòu)上,承受徑向負(fù)荷后產(chǎn)生軸向分離,所以,將2 個(gè)軸承對(duì)置使用,或二個(gè)以上成對(duì)雙聯(lián)使用。單列向角接觸球軸承,可以使用預(yù)壓方法提高剛性,因此,適用于高旋轉(zhuǎn)精度的機(jī)床主軸等。一般,接觸角30°(代號(hào)A)及40°(代號(hào)B)的角接觸球軸承保持架,依照表1。但根據(jù)不同的條件也使用合成樹脂保持架或聚酰胺成型保持架。尺寸表記載的基本額定負(fù)荷,以表1 保持架區(qū)分為基準(zhǔn)。

Single-Row Angular Contact Ball Bearings (Pressed Steel Cages & Machined Brass Cages)
Since these bearings have a contact angle, they can sustain significant axial loads in one direction together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced; therefore, two opposed bearings or a combination of more than two must be used.
Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools, for which high running accuracy is required.
Usually, the cages for angular contact ball bearings with a contact angle of 30° (Symbol A) or 40° (Symbol B) are in accordance with Table 1, but depending on the application, machined synthetic resin cages or molded polyamide resin cages are also used. The basic load ratings given in the bearing tables are based on the cage classification listed in Table 1.
