This standard specifies the method of indicating rolling bearings. This standard is mainly applicable to standard rolling bearings whose shape and structure do not need to be accurately indicated in the assembly drawing. Non-standard rolling bearings can also be used as a reference.

This standard is based on 508826-1:198 Technical drawings - Part 1: General commercial representation and 150882%-2:198 Technical drawings - Part 2: Detailed table of bearings. If the technology is equivalent, the international standard is adopted.
This standard From the implementation, GB4458.1--84 Kaiji City Drawing Method Appendix 4 and Appendix H will be abolished to meet the needs of international trade, technology and economic exchanges. Special methods for indicating dynamic bearings in mechanical specifications: In my country's national mechanical standards, this type of standard (4459\5026-5026-2 will be converted into a national standard according to the principle of "one item, one standard") will be formulated as a standard. At the same time, the following important contents will be added as needed; 1.5.1.3 specifies the table method for the auxiliary parts of the bearing: 2. In the table 1.4, the table method for the auxiliary parts of the bearing is added: 3. In the table 5-1., the table method for the auxiliary parts of the bearing is added: 4. The table 3 adds the method for the "three-point touch" and "four-point connection" of the cylinder and the nut. The annexes of this standard are for reference only. The standard is issued by the Ministry of Machinery Industry.
This standard is under the jurisdiction of the National Technical Drawing Standardization Technical Committee. The drafting unit of this standard is the mechanical engineering The industry's Mechanical Standardization Research Institute, Dalian Zhuzhui College, Changzhou Technical Normal College, the promoters of this standard are: Bai Xiaodong, San Kui, Qiang, Ji Pan, Huang, Ding Siying.

ISO International Standardization Organization (TSO) is the most common international standardization organization (TSO) in the industry. The work of formulating national standards is usually completed by 13 technical committees. Each member has the right to participate in the work of the committee if he or she is interested in a project established by the technical committee. 5 International organizations (official or unofficial) that maintain contact may also participate in the relevant work. In the field of technical standardization, the IS Center maintains close cooperative relations with the Interregional Committee (IE). The international standard draft adopted by the technical committee is submitted to the member groups for voting. It needs to obtain the consent of 75 participating countries before it can be officially released as an international standard.

The cloud standard is mainly applicable to the manufacturer of the car table. The standard of the rolling stock is the standard of the rolling stock. The standard of the rolling stock can also be referred to. 2 Reference standards
The following standards contain the provisions of the standard referenced in this standard. When this standard is issued, the standard shown in the standard is valid. All standards are revised by the department meeting and the standard is marked with the vehicle mark. All parties should discuss the possibility of using the following standards to prove the latest release.

5.1.1 In the special specification: when there is no external wheel bearing or load characteristic structure to be accurately represented, a rectangular line and a 1-shaped symbol located in the center of the line can be used. The general drawing method should be drawn on both sides of the shaft (Figure 5.1.2). If the shape of the rolling bearing can be accurately represented, its surface should be drawn, and the cross symbol should be drawn on the single cross surface of the wheel. The cross symbol should be connected with the wheel surface line. Figure 5.1.3 When the driven shaft has accessories or lifting parts, this part or this part can only show its outer shape (Figure 6). 5.1.4 When it is necessary to indicate the rolling bearing's bearing width and bearing plate, the force method of Figure 7 and Figure 8 can be used to draw the bearing. If there is no bearing inside or outside the bearing, the method of Figure 9 can be used to add a cross symbol to the cross number to indicate the direction of the bearing. 5.1.5 In the left assembly, if the bearing's bearing rate is not shown in the figure, this part can be drawn horizontally (Figure 10). 5.2 Holding method
52.1 In the figure, if it is necessary to effectively show the bearing rate of the shaft, the short line can be used to express the characteristic element symbol combination of the bearing (Table 1). The characteristic method of the bearing is shown in Table 2. The characteristic element symbol combination of the bearing is shown in Table 3. The characteristic element symbol combination of the bearing and the bearing plate should be drawn on both sides of the shaft.
5.2.2 In the vertical box bearing shaft The projection surface of the line is shown on the figure. Regardless of the shape of the rolling element (. Du, needle, etc.) and the size, it can be made according to the 11-tooth system
