Internal Combustion Engines--Piston Rings--Oil Control Rings(Cancelled Jun 2008)
This SAE Standard is equivalent to ISO Standard 6625.
Differences, where they exist, are shown in Appendix A.
This SAE Standard specifies the dimensional features of S, G, D, and DV oil control piston ring types.
The normal range for the axial width of oil control rings (2.5 to 8 m inclusive) is divided into 0.5 or 1.0 increments. In Table 7, dimensions in inch units are given for oil control rings with axial width 4.75 m (equal to 3/16 in) for existing applications.
The requirements of this document apply to oil control rings for reciprocating internal combustion piston engines up to and including 200 mm in diameter. They may also be used for piston rings of compressors working under similar conditions.
Rationale:SAE J2002 is being discontinued because the content of this standard is also contained in ISO 6625. Therefore, to eliminate duplication and confusion in coordinating the standards between ISO and SAE, this document will be discontinued. The SAE Piston and Ring Standards committee will now continue to support ISO in updating the standards as appropriate.
