5、J1926-1 FEB2010Connections for General Use and Fluid Power - Ports and Stud Ends with ASME B1.1 Threads and O-Ring Sealing - Part 1: Threaded Port with O-Ring Seal in Truncated HousingRATIONALEThis specification was revised to clarify where the d5 dimension is measured.FOREWORDSAE J1926 consists of
6、the following parts, under the general title:Connections for general use and fluid power Ports and stud ends with ASME B1.1 threads and O-ring 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 Ends Part 4: External
7、Hex and Internal Hex Inch Port Plugs - Dimensions, Design, Test Methods and RequirementsThese standards define performance requirements, dimensions, and designs for port and stud end connections for heavy-duty in Part 2 and light-duty in Part 3. Significant testing through over 50 years of use has c
8、onfirmed the performance requirements of these ports and stud ends.In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within an enclosed circuit. In general applications, a fluid may be conveyed under pressure. Components are connected through
9、their threaded ports by fluid conductor fittings to tubes and pipes, or to hose fittings and hoses.Ports are an integral part of fluid power components such as pumps, motors, valves, cylinders, etc.1. SCOPEThis part of SAE J1926 specifies dimensions for fluid power and general use ports with inch th
10、reads in accordance with ASME B1.1 for use with adjustable and nonadjustable stud ends shown in SAE J1926-2 and SAE J1926-3.Ports in accordance with this part of SAE J1926 may be used at working pressures up to 63 MPa for nonadjustable stud ends and up to 40 MPa for adjustable stud ends. The permiss
11、ible 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 ends in accordance with ISO 1179, ISO 9974, and ISO 11926
12、shall not be used for new designs in hydraulic fluid power applications.SAE INTERNATIONAL J1926-1 SEP2016 Page 2 of 52.
