Each type of bearing can be deep-groove, spherical or insert. Deep-groove bearings are the most common. Insert bearings are deep-groove bearings which, like spherical bearings, effectively support misalignment.
每种类型的轴承都可以是深沟轴承、球面轴承或嵌件轴承。深沟轴承是最常见的。嵌件轴承是深沟轴承，与球面轴承一样，可有效支撑不对中。
They differ from spherical bearings in that they have a smaller swivel angle. The larger the swivel angle, the more the bearing will withstand misalignment.
它们与球面轴承的不同之处在于它们具有较小的旋转角度。旋转角度越大，轴承承受的不对中就越大。
Another factor to consider: depending on the use, you will need a rotating shaft (for example wheel drive bearings for cars) or a rotating hub (like for washing machine bearings).
另一个需要考虑的因素是：根据用途的不同，您将需要一个旋转轴（例如汽车的车轮驱动轴承）或一个旋转轮毂（例如洗衣机轴承）。
Then you will need to pay attention to how the bearings are assembled. If two bearings are too close together, you should use the O-assembly method so that the bearings do not interfere with each other. If this is not the case then the X-assembly method is perfectly suitable.
然后，您需要注意轴承的组装方式。如果两个轴承靠得太近，则应使用 O 型装配方法，以免轴承相互干涉。如果不是这种情况，那么 X 组装方法非常合适。
Finally, each bearing has specific dimensions. These dimensions, expressed in mm, are subject to international standards. We therefore advise you to pay attention to the bore of the bearing, i.e. the inner diameter (always represented by the letter d), the outer diameter (represented by the letter D) and the width (represented by the letter B).
最后，每个轴承都有特定的尺寸。这些尺寸以毫米表示，符合国际标准。因此，我们建议您注意轴承的孔径，即内径（始终用字母 d 表示）、外径（用字母 D 表示）和宽度（用字母 B 表示）。
