1.Structural characteristics
Single-row angular contact ball bearing can only support the axial load of unidirectional action. Under the action of radial load, there will be an axial force in the bearing, which needs to be adjusted by a reverse force. Therefore, this bearing generally needs to rely on a second bearing to balance. Single-row angular contact ball bearing can be loaded with more steel balls, so that the bearing has a higher carrying capacity. The contact angle has 1525
40 three types, suffix code forCACB. Single-row angular contact ball bearing include non-separated type and separated type. Non-separation type bearings are divided into three series of standard, high speed and super high speed according to different applications; The inner ring and outer ring of the separation type bearing can be installed respectively, only used in the parts with limited installation position such as magneto, this kind of bearing is also called magneto bearing.
The non-separated bearing cage, the inner ring guide fiber reinforced phenolic resin cage is the standard structure, the bearing code is not marked. When other retainers are used, the corresponding suffix code shall be indicated:
TA: Outer ring guide fiber reinforced phenolic resin cage
TN: Reinforced nylon 66 mold injection cage
M: Brass turning cage
Separate type bearings (i.e.. magneto bearings) are mainly made of reinforced nylon 66 mold injection cages. If required, bearings made of stamped cages with brass plates are available. Bearings with reinforced nylon 66 mold injection cages are suitable for most applications, and can work normally at -30C-- 120C.
According to the structural characteristics of single-row angular contact ball bearings, this type of bearings are usually two or above two same type of bearings combined together to use, the specific collocation method is shown in Table 1, the structural characteristics of pairs of double bearings are shown in Table 2, and the characteristics of other collocation methods can also be referred to Table 2. Pairing or multi-pairing bearing, in th application of the insallation must apply a certain top load. Select the appropriate pre-load can improve the rigidity ofthe spindle system, reduce the temperature rise, improve the processing accuracy of the system, bearing preload is divided into light (A), medium (B), heavy (C) three grades, users can be selected according to the actual working conditions of the spindle system. Every series bearings back- to-back, face-to-face preload values are shown in Table3- Table 6, 40" contact angle (suffix B) single-row angular contact ball bearings according to different uses, according to two types of production. The first type is suitable for configurations where only one bearing is placed in each bearing position. The other type is suitable for a configuration in which two or more bearings are mounted together in an arbitrary manner (universal pairing). 196 is used to universal pairing bearings and manufactured so that they can be installed next to each other in a free manner, so that predetermined axial clearance and uniform load distribution can be achieved without the use of adjusting gaskets or similar devices. Indicates that the rear delay of the surge pair bearing is CB, where C indicates that there is clearance, and B indicates the size of the clearance value. Bearings with small or large clearance are also available (suffixes CA and CC, respectively). In the case of preload bearings, light preload, medium preload and heavy preload are identified by suffixes GA, GB, GC, respectively (G stands for preload or negative clearance). When ordering bearings such as 7206BTNCB for general pairing, the number of individual bearings required must be specified.
