Foreword
GB/T 34633 "plain bearing shell bearing" is divided into three parts.
--- Part 1. Block type plain bearings;
--- Part 2. Offset flanged plain bearings;
--- Part 3. Central flange bearing.
This section GB/T 34633 Part 1.
This section adopts the redrafted law to amend the use of ISO 11687-1.1995 "sliding bearing housing support plain bearings Part 1. Block
Type sliding bearing ".
Technical differences between this part and ISO 11687-1.1995 and the reasons for this.
--- On the normative references, this section made a technical difference with the adjustment to adapt to China's technical conditions, adjust the situation
Concentration reflected in Chapter 2 "Normative references", the specific adjustments are as follows.
● Equivalent to the international standard GB/T 131 instead of ISO 1302;
● Equivalent to the international standard GB/T 1184 instead of ISO 2768-2;
● Equivalent to the international standard GB/T 1804 instead of ISO 2768-1;
● Equivalent to the international standard GB/T 6414 instead of ISO 8062;
● Equivalent to the use of international standards GB/T 9439 instead of ISO 185;
● Replacing ISO 3755 with revision GB/T 11352 using international standards.
--- Chapter 3 increased the form of bearing insulation code to improve the description of the bearing type.
--- Chapter 6 "Materials", as a result of ISO 630.1980, ISO 683-11.1987, ISO 426-1.1983, ISO 426-2.1983
Obsolete, and our country does not correspond to the material grades, so the use of the domestic industry are using our national standards GB/T 699, GB/T 1174,
GB/T 1348, GB/T 8740 and GB/T 17107 in the material instead of the international standard grades of materials,
Should be the actual production and use of the country; in this standard quoted by the national standard content and international standards corresponding to the same conditions
Under the non-equivalent use of GB/T 9439 and GB/T 11352 instead of ISO 185 and ISO 3755, respectively, to meet the domestic
Need for standardized work exchange.
This part is proposed by China Machinery Industry Federation.
This part of the National Standardization Technical Committee of the sliding bearing (SAC/TC236) centralized.
This section is responsible for the drafting unit. Machine Productivity Promotion Center, Zhejiang Branch Bearing Technology Co., Ltd. Shanghai Branch.
Participated in the drafting of this section. Hunan Zonta Industrial Technology Co., Ltd., Zhuji City, Zhejiang Bearing Plant Co., Ltd., Zhejiang Province axis
Watts Co., Ltd., Dongfang Electric Group Dongfang Electric Co., Ltd., Harbin Electric Works limited liability company sliding bearing division.
This part of the national standardization of sliding bearings Technical Committee is responsible for interpretation.

3 bearing type
Block type bearings can be characterized by the following text symbols.
Figure 1 and Figure 2 is a typical schematic seat bearing. According to the installation size can be divided into its model number 9 to 28 and 35 to 71, the figure
The symbols show only the form of their representation, when ordering, the complete description of the following order.
Due to design (such as size restrictions) and economic reasons, for the 35 ~ 71 bearing A-type thrust structure, the size can only be in accordance with Table 3
