needle roller and angular contact ball bearings.

Thrust spherical roller bearings: rolling body is convex or concave spherical roller thrust bearing. Convex spherical roller bearing ring raceway is spherical shape, a concave spherical roller bearing shaft ring raceway is spherical shape.
Bearings: Spherical bearings and pedestal combined with a component, in line with the bearing axis parallel to the support surface of the mounting screws on the bottom.
Bearing joints: the sliding contact surface of the spherical, mainly applicable to swing movement, tilting movement and rotation of spherical plain bearings.
taper roller bearing: a set of bearing two or more simultaneously by said bearing structure combination of rolling bearings. Such as needle roller and thrust cylindrical roller bearings, needle roller and thrust ball bearings, needle roller and angular contact ball bearings.
Other Bearings: In addition to the above other than the structure of the rolling bearing.
1. Basic Code bearings
A basic code used to indicate the bearing bore diameter series, the width of the series and type, generally up to five numbers, first described as follows:
1) bearing bore from the right with the basic code first, H digits. Of the common diameter d = 20 ~ 480mm inner diameter of the bearing is generally a multiple of 5, the two numbers indicate the inner diameter of the bearing to the quotient divided by 5, 04 such that d = 20mm; 12 so that d = 60mm. The inner diameter of 10mm, 12mm, 15mm and 17mm bearings, inner code in order to 00,01,02 and 03. For less than 10mm diameter and greater than 500mm bearings, inner representation otherwise, can be found GB/T272-93.
2) The diameter of the bearing series (ie, the same structure, the same inner diameter of the bearing outside diameter and width in the change series) with a basic code the third digit from the right. For example, for radial bearings and thrust bearings to the heart, 0,1 indicates special light series; 2 represents light series; 3 shows the series; 4 represents heavy series. Comparison between the size of the series as shown below. In addition to using a thrust bearing expressed special light series, the other with radial bearings expressed unanimous.
