Helical Compression and Extension Spring Terminology

2016-08-02
CURRENT
J1121_201608
The following recommended practice has been developed to assist engineers and designers in the preparation of specifications for the major types of helical compression and extension springs. It is restricted to a concise presentation of items which will promote an adequate understanding between spring manufacturer and spring user of the major practical requirements in the finished spring. Closer tolerances are obtainable where greater accuracy is required and the increased cost is justified. For the basic concepts underlying the spring design and for many of the details, see the SAE Information Report MANUAL ON DESIGN AND APPLICATION OF HELICAL AND SPIRAL SPRINGS, SAE HS 795, which is available from SAE Headquarters in Warrendale, PA 15096. A uniform method for specifying design information is shown in the TYPICAL DESIGN CHECK LISTS FOR HELICAL SPRINGS, SAE J1122.

Performance Test Procedure - Ball Joints and Spherical Rod Ends

2012-10-15
CURRENT
J1367_201210
The purpose of this test procedure is to provide a uniform method of testing commercial spherical rod end bearings to determine their performance characteristics under specific application situations. This procedure is an extension of the dimensional requirements for spherical rod end bearings as set forth in SAE J1120 and J1259. The loads, number of cycles, definition of failure, etc., are to be agreed to by the user and supplier. This procedure can also be used as the basis for testing ball joints covered by SAE J490.

Ball Stud and Socket Assembly - Test Procedures

2012-10-15
CURRENT
J193_201210
The test procedures describe a method to laboratory test suspension and steering system ball stud and/or socket assemblies for functional characteristics. This procedure is an extension of SAE J491b recommended practice on dimensional recommendations for ball studs towards a vehicle application. The tests are conducted either on ball studs individually or on complete integral assemblies representing the application.

Technical Report on Low Cycle Fatigue Properties Ferrous and Non-Ferrous Materials

2002-08-13
HISTORICAL
J1099_200208
Information that provides design guidance in avoiding fatigue failures is outlined in this SAE Information Report. Of necessity, this report is brief, but it does provide a basis for approaching complex fatigue problems. Information presented here can be used in preliminary design estimates of fatigue life, the selection of materials and the analysis of service load and/or strain data. The data presented are for the “low cycle” or strain-controlled methods for predicting fatigue behavior. Note that these methods may not be appropriate for materials with internal defects, such as cast irons, which exhibit different tension and compression stress-strain behavior.
