The People's Republic of China Machinery Industry Standard JB/T3574-1997 Rolling Bearings Issued on April 15, 1997 Product Marking Implementation on January 1, 1998 The Ministry of Machinery Industry of the People's Republic of China JB/T3574-1997 is the international standard for rolling bearings. During the revision of the standard, the use of standard seats, terminology, new codes for auxiliary bearings, addition of auxiliary system marks, location marks, packaging marks, etc. were added. From the implementation of the standard, the standard will be replaced by B35-1997. The standard is proposed and issued by the National Hydraulic Industry Technical Committee. The first unit: the price of the industry Bailu Yangyang Institute. This standard was first issued by the People's Republic of China in 2002 and revised in 2003. 1 Scope
Machinery Industry Standard of the People's Republic of China
Rolling Bearing Product Marking
This standard fully regulates the marking on the bearing and its packaging, as well as the marking of various types of exciting shaft components and common packaging devices, including: packaging products, inner packaging, outer packaging content. 2 Reference standards | |tt||JHT3574—1997

The meaning of the main terms used in this standard is in accordance with GBS3C and GB4125, 4 Basic content of marking
The requirements should include the bearing code and the manufacturer code (or reduction code), and the manufacturer code can be increased if necessary. Before the production is recognized, the marking
1.1.1 Inseparable type, or the basic content to be indicated at one end of the differential drawing, in order to distinguish the reference end, the non-standard process number mark on the drawing is allowed.
4.1.2 Separable reduced shaft components should be marked on the actual drawing with rolling elements under the actual drawing, 4.1.3 Code of closed bearings Sealing code or anti-seat code can be simplified. For example, 2Z can be abbreviated as Z: 2R5 can be RS.
4.2 Packaging container
The complete code of the packaging container and the inner packaging container shall be marked with the full code of the packaging container, the quantity, the production year (or the length of the packaging container), the total code (code), the number of packaging containers can be omitted, and the outer packaging should be short according to the provisions of B559738 Chapter 5.1. The packaging container is generally marked on the end of the packaging container. It can also be marked on the packaging container according to the product requirements. The outer surface, the boundary, the sealing cover or the dust cover are kept. 5.1.2 For the type of packaging container, the type of packaging container can be marked according to the type in Table 1.

5.1.3 When the effective width of the end face of the marked component is greater than 2.0, the mark shall be on the outer surface of the bearing. When the mark is on the shaft mark, it can be selected and marked on the packaging. 5.2 Packaging Containers
For single and inner packaging containers, the original purchase mark is on the upper surface or the surface: while for packaging containers, the mark is on the (wooden) purchase. In addition, according to the agreement between the manufacturer and the order, the inner and outer packaging can be recorded with the record sheet, label, etc. or marked on the container during production!
i Marking Methods
6.1 Bearings
The ball method, electrolytic filtration, laser method, etc. can be used for the detection of bearings. Under special circumstances, the chemical method can also be used. The chemical method is only used for checking:
a) Trial products with small quantities:
above) are used to supplement the group code and pairs, the relevant numbers and marks of multi-capsule bearings, 6.2 Public equipment
The inner product specified in the second part is marked by printing, typing or other easily disappearing methods. 7.1 The characters on the markings shall be standardized and consistent, and shall meet the requirements of the manufacturer and product design department. 7.2 The height of the characters marked on the bearings shall be selected according to the following heights: 0.5, 0.7, 1, 1.2, 1.5, 3, 2.5. 3, 4, 5 m- According to the specifications of the product, the same size of characters shall be used on all parts of the bearing, and the size of the characters shall not be used. The height shall be as close as possible to the height of the two markings on the same base. 7.3 The markings shall be complete. 7.4 The lines shall be uniform. 7.5 The center circle of the bearing mark shall not be too low, and the distance shall not be too long. The shape, line height and distance of the markings shall meet the requirements of the manufacturer. According to the regulations of the design department of the manufacturer, the surface of the bearing and other related standards are allowed to be marked, and there are no other marks. If the customer has special requirements, the mark can be negotiated with the manufacturer.
