This standard specifies the dimensions, tolerances, radial clearance and technical requirements of E, EH, G, GH and K series rod ends. The structural design of rod ends does not have to fully comply with the illustrated structure of this standard, but the dimensions, tolerances and radial clearance should be consistent with the provisions of this standard. This standard applies to rod ends with different combinations of sliding materials for production, inspection and user acceptance by manufacturers. This standard does not apply to rod ends for aircraft frames and special rod ends directly on hydraulic cylinders.

This standard is equivalent to 1S012210:1018. This standard adds the eighth factor compared with 1324:1-4:1. This standard combines GBSG1988 rod end bearing outline dimensions and G512221991 rod end bearing outline dimensions and specifications, and modifies the main technical contents of the revision: 1) adds the structural type and corresponding dimensions of the rod end bearing; 2) adds the dimensions, tolerances and specifications of the GT and FH series, and increases the VVr tolerance value of the T series: 3) 4) The original series is changed from K to K: 51 and the fixed text is added. The size series of the first plate and the end joint bearing are added. The special column of the bearing type in the table is deleted. This standard is based on the table of 4 effects, public security G/T111938. B/222--1391. This standard is proposed by the China Machinery Industry Federation, and this standard is the standard of the national rolling bearing standardization technical requirements. The unit of this standard is: Ziyin Oil Bearing Research Institute. The main drafter of this standard is Bangbao. This standard was first issued 4 years ago. The first revision was in 1981 and the second revision was in 1989. 1

This standard specifies the dimensions, tolerances and technical requirements of H, CH and K series rod end bearings. The structural design of the rod end and the shaft does not have to fully conform to the structure shown in the figure of this standard, but the dimensions, tolerances and radial limits are consistent with the provisions of this standard.
This standard is applicable to rod end bearings with different drive materials, and is provided for production, inspection and collection by manufacturers. This standard promotes the use of aircraft frame rod end bearings and special rod end bearings for connection to pressure cylinders. 2 Referenced standards

General technical conditions
This standard uses GE/T 2514 and G%/T 4-99. Unless otherwise specified, the symbols and (except tolerance symbols) shown in this standard indicate nominal dimensions.
Design: The size of the upper dimension of the relative slip joint depth can be different. The manufacturer can determine the type and structure of the lubrication interface by himself. Figure 1M type external screw light is still X control

Similar color blood. Refers to the degree of inclination between the inner and outer contact surfaces. When the inner and outer contact surfaces are not less than the theoretical contact area when the bearing rings are parallel to each other, the bearing will measure the adjacent zero position; the limit is also one. 2. Single internal deviation
Single radial plane average internal deviation
4. Size series
Rod joint bearings are divided into two basic size series. Size series E and G are suitable for rod joint shafts with shaped inner holes or centrifugal joints. In size series F and G, according to the type of structure, they are also divided into external thread and internal thread, ordinary type or reinforced type or welded type.
The K series is a nearly universal joint bearing with a K series radial joint shaft installed in the shape of a -1. In the inch series, the rod end bearings have different structures: the rod end joint shaft can also be divided into two types (with external thread or internal thread, see Figure 5). You can choose a combination of dynamic materials. 5 Overall dimensions
