Bearing can be divided into two categories: one kind is roller bearing;
The application is broad, is to introduce the contents of the book.
Although the types of rolling bearing is various, but has become a 'standard', playing a unified code form, when used according to the sample selection.
A, the classification of rolling bearing (
A)
According to the size of the bearing size classification of bearing is according to the size to determine the nominal diameter, specific provisions are shown in table 1

Table 1 -
1 according to the size of the bearing type classification class micro small small medium large very large nominal diameter size range/mm 2628 - or less

430 440 or by a plane perpendicular to the axis bearing roller center called bearing radial plane;
Contains bearing the centerline of the plane is called the axial plane.

The national standard GB/T 271 -
2008 'classification of rolling bearing, roller bearing can bear the load according to its direction, nominal contact Angle and rolling body shape can be divided into three categories, a total of 14 kinds of basic types, see table 1

According to the structure of the bearing or different classification according to the structure of the nominal contact Angle or nominal contact Angle is different, the main classification are shown in table 1
