6、 within a global market and ensuring that companies can remain competitive in an international market, it is the intent to convert to metric hex sizes which will: lead to one global system guide users to preferred system reduce complexity eliminate duplications The optional inch hexes now contain th
7、e note “NOT TO BE USED FOR NEW DESIGN” in accordance with the Metric Hex Resolution approved during the March 2008 FCCTC meeting.

8、g sealing: Part 1: Port with O-Ring Seal in Truncated Housing Part 2: Heavy-Duty (S Series) Stud Ends Part 3: Light-Duty (L Series) Stud EndsSAE INTERNATIONAL J1926-2 SEP2016 Page 2 of 15These standards define performance requirements, dimensions, and designs for port and stud end connections for he
9、avy-duty in Part 2 and light-duty in Part 3. Significant testing through 25 years of use has confirmed the performance requirements of these ports and stud ends (up through size -24). SAE 1926-2 stud ends up through size -24 were originally designed for high pressure connectors of SAE J1453 (current
10、 SAE J1453-3). Size -32 was developed later with performance verification via round robin testing by FCCTC-C1 committee members.In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within an enclosedcircuit. In general applications, a fluid may b
11、e conveyed under pressure. Components are connected through their threaded ports by stud ends on fluid conductor fittings to tubes/pipes, or to hose fittings and hoses.1. SCOPEThis part of SAE J1926 specifies dimensions, performance requirements, and test procedures for adjustable and nonadjustable
12、heavy-duty (S series) stud ends with ASME B1.1 threads for use in fluid power and general applications and the O-rings used with them that are currently not listed in SAE J515.Stud ends in accordance with this part of SAE J1926 may be used at working pressures up to 63 MPa for nonadjustable stud end
13、s and up to 41.3 MPa for adjustable stud ends. The permissible working pressure depends upon materials, design, working conditions, application, etc.For threaded ports and stud ends specified in new designs for hydraulic fluid power applications, only ISO 6149 shall be used. Threaded ports and stud
14、ends in accordance with ISO 1179, ISO 9974, and ISO 11926 shall not be used for new design in hydraulic fluid power applications.NOTE: This document specifies inch as well as metric hexes for the stud ends. Therefore, any product drawing specifying stud ends in accordance with this document must spe
15、cify hex type, inch or metric, to assure getting intended hex.Stud ends or parts specified before January 1, 2010 using this standard, shall be supplied with inch hexes, unless otherwise specified.Conformance to the dimensional information does not guarantee rated performance. Each manufacturer shal
16、l perform testing according to the specification contained in this document to ensure that components made to this document comply with the performance rating.Appendices A and B of this document are informative.2.

35、NITIONSFor the purpose of this part of SAE J1926, the definitions given in ISO 5598 and the following shall apply.3.1 ADJUSTABLE STUD ENDA stud end connector that allows for fitting orientation before final tightening of the locknut to complete the connection. This type of stud end is typically used
36、 on shaped fittings (e.g., tees, crosses, and elbows).3.2 NONADJUSTABLE STUD ENDA stud end connector that does not require specific orientation before final tightening of the connection because it is typicallyused on straight fittings.4. STUD END4.1 Size DesignationThe stud ends shall be designated
37、by SAE J1926-2 and the thread size, separated by a colon, for example, SAE J1926-2:1/2-20. Products drawings specifying this stud end shall have the type of hex, inch or metric, listed.4.2 Reduced Size Stud Ends for Jump Size ConnectorsFor jump size connectors where the hex size of the other end, e.
38、g., tube/hose end, is larger than the stud hex “V” in Tables 1and 6, a shoulder may have to be turned to the appropriate diameter and length to avoid interference with the port spot face. For details, see appropriate connector standard, e.g., SAE J1453-3 .4.3 AssemblyFor proper stud end assembly, fo
39、llow instructions in SAE J2593.5. REQUIREMENTS5.1 DimensionsHeavy-duty (S series) SAE J1926-2 stud ends shall conform to the dimensions in Figures 1A and 1B and Tables 1 and 6.Hex tolerances across flats shall be according to ISO 4759-1 product grade C.5.2 Working PressureHeavy-duty (S series) stud
40、ends made of low-carbon steel shall be designed for use at the working pressures given in Table 2.CAUTION: The pressures for sizes -40 (3-12 UN) and -48 (3 -12) are based on calculations for guidance only.SAE INTERNATIONAL J1926-2 SEP2016 Page 6 of 15Figure 1A - Adjustable SAE J1926-2 heavy-duty (S
