Angular contact bearings are the type most commonly used in very high-speed spindle design. These bearings provide precision,load carrying capacity,and the speed needed for metalcutting.Angular contact ball bearings have a number of precision balls fitted into a precision steel race, and provide both axial and radial load carrying capacity when properly preloaded.
In some cases,tapered roller bearings are used because they offer higher load carrying capacity and greater stiffness than ball bearings.However,tapered roller bearings do not allow the high speeds required by many spindles.
Angular contact ball bearings are available with a choice of preloading magnitude,typically designated as light,medium,and heavy.Light preloaded bearings allow maximum speed and less stiffness.These bearings are often used for very high-speed applications,where cutting loads are light.

以下是用有道桌面词典翻译的，你凑合着看吧！（我是没看懂！！！！）
角接触轴承类型中最常用的设计非常高速主轴。这些轴承精度、承载能力提供所需的速度,metalcutting角接触球轴承有一定数量的精密球装一个精密的钢竞赛,提供的轴向和径向负荷承载能力适当的预紧。
在某些情况下,圆锥滚子轴承被使用,因为它们提供更高的承载能力和更大的刚度比球轴承然而,圆锥滚子轴承不允许高速锭子所需要的多。
角接触球轴承都是可以选择的预压大小,通常被指定为轻型、中型和重型轻载预压轴承允许最大速度和更少的刚度这些轴承通常用于非常高速切削载荷应用,是光
