Book Description
This SAE Standard is equivalent to ISO Standard 6627 TR. Differences, where they exist, are shown in Appendix A with associated rationale. This SAE Standard specifies the dimensional features of commonly used oil control rings having two steel segments (rails) separated and expanded by one steel expander/spacer. The segments vary in width from 0.4 to 0.6 mm. The assembly width ranges from 2.5 to 4.75 mm. The 4.75 mm width is equivalent to existing 3/16 in applications. Expander design will vary considerably with piston ring manufacturer. The total circumferential deflection and the piston groove depth should be considered when designing these oil rings to optimize the fit of the ring assembly into the piston groove. This document applies to oil control rings up through 125 mm for reciprocating internal combustion engines. It may also be used for piston rings of compressors working under similar conditions.

Book Description
This SAE Recommended Practice is equivalent to ISO Standard 6626.Differences, where they exist, are shown in the appendix with associated rationale.This document specified the essential dimensions of piston ring types DSF-C, DSF-CNP, SSF, GSF, DSF, DSF-NG, and SSF-L coil spring loaded oil control rings.For the cast iron part the recommended material is class 10 according to SAE J1590. For special applications material classes 20 to 50 may be used.Variation in face design and spring groove from these may be used, as recommended by individual manufacturers, in plain or chromed versions.The tangential forces of coil spring loaded oil control rings can be varied over a wide range. Explanations and recommendations are given in Section 6.The normal range for axial width of coil spring loaded oil control rings (3 to 8 mm inclusive) is divided into 0.5 or 1.0 mm steps. In Tables 15 to 20 dimensions are given for coil spring loaded oil control rings with an axial width of 4.75 mm (i.e. 3/16 in) for existing applications in inch units.This document applies to coil spring loaded oil control rings up to 200 mm inclusive for reciprocating internal combustion engines. It may also be used for piston rings of compressors working under similar conditions.

Book Description
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.

Book Description
This SAE Standard specifies the quality aspects that are capable of definition but not normally found on a drawing specification. The difficulty of trying to define in absolute terms the quality attainable in normal commercial manufacture of piston rings is well known. In this document the commonly encountered aspects of quality in terms of casting defects and other departures from ideal are quantified. Many minor defects are clearly quite acceptable; other defects because of size or numbers are inadmissible. This document covers the following: a) Single piece piston rings of grey, carbidic, malleable, spheroidal graphite cast iron or steel; b) Multipiece pistong rings (oil control rings) consisting of cast iron parts and spring components; c) Single piece and multipiece rings of steel, i.e., oil control rings in the form of strip steel components or steel segments (rails) with spring expander components. In addition to specifying certain limits fo acceptance relating to inspection measuring principles (covered by SAE J1589) this document also covers those features for which no recognized quantitative measurement procedures exist and which are only checked visually with normal eyesight and without magnification. Such features (superficial defects) are additional to the standard tolerances of ring width, radial wall thickness, and closed gap. The requirements of this document apply to all rings up to and including 200 mm diameter covered by the above classification for both reciprocating internal combustion engines and compressors.SAE J1996 is being discontinued because the content of this standard is also contained in ISO 6621-5. 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.
