This standard specifies the series of standard dimensions (diameter, length, height, etc.) commonly used in the machinery manufacturing industry within the range of 0.01 mm to 20,000 mm. This standard applies to the main dimensions with interchangeability or serialization requirements (such as installation and connection dimensions, matching dimensions with tolerance requirements, nominal dimensions that determine the product series, etc.). Other structural dimensions should also be adopted as much as possible. This standard does not apply to dependent variable dimensions derived from main dimensions, dimensions between process steps in the process, and dimensions specified in corresponding standards.

The standard sizes specified in this standard are based on the GB/T32-2000 priority numbers and priority number systems and GB/T32-2000 priority numbers and priority number systems. This is conducive to the coordination, optimization and elimination of the narrow and different sizes in the machinery manufacturing industry. This standard mainly refers to the GB/T2k22-19H: standard size 1> the writing rules of our standard This standard replaces GB/2822-1U.3. This standard is proposed by the National Technical Committee for Standardization of Product Size and Geometry Specifications and drafted by the following units: China Machinery and Fuel Institute, China Machinery Science and Technology Promotion Center ... GB/T2822—2005
This standard defines the series of commonly used standard scales (diameter, length, height, etc.) in the range of 0.01mm~20000mm in the small machinery manufacturing industry.
This standard uses the main scales that are interchangeable or require serialization (such as installation and connection dimensions, matching dimensions with tolerance requirements, nominal dimensions that determine product series, etc.), and other structural dimensions should also be used as much as possible. This standard does not apply to dependent variable scales derived from main dimensions. Only small-scale works with dimensions that have been specified in corresponding standards shall have corresponding standards. 2. Specification of cited documents

4.1 When selecting standard size series and single size, you should first select: H in the required R series and give priority to the basic series and its single size in the order of R10.R20.R40. 4,2 If you must choose, you can select the standard size in the corresponding R series. The selection order is K5, R20, Ra4o
4.3 In addition to the basic series listed in each table, you can also use a composite series to derive a series derived from a certain basic series.
